Low cloud. Rain.

Approx 1700. Red white "rescue" chopper low, direct over my location, about 8 miles east of Strandhill airport. It was flying south. So it wasn't rescuing anyone at sea, wasn't going to Dublin. A flight to the hospital in Galway?

But why would they fly to Galway when the hospital in Sligo is just as bad?

Any info or theories would be appreciated.

Training flight perhaps. We sometimes see one over Co Cork, seemingly going nowhere that a coast guard chopper has a need to go.

Humidity is the amount of moisture that is held in the air as water vapour, the warmer the air the more water it can hold until the point is reached where the air becomes saturated and it can hold no more. We usually talk about the amount of moisture in the air as relative humidity, this is the percentage of water that is being held relative to what it can hold, hence 50% RH is where the air holds only half the water it is capable of, at that temperature.

If we take a parcel of air at 50% RH and increase the temperature then the RH will fall, converesely, if we take a parcel of air and cool it the RH increases and this is what happens above a wing. The faster flowing air experiences a drop in pressure, leading to it expanding and cooling. This cooling raises the RH of the air to above 100%, leading to condensation forming.

Therefore the higher the RH of air the more likely the moisture is to condense when subjected to further cooling, and also the longer the trails will take to disappear again.

In the 70s and 80s we would buy a used bus in the UK and the engine would last at most a year .
the English operator sometimes kept in touch to see would he sell another as the Irish paid more and sometimes had cash .
all the English loved selling to the Irish -- when we would inform them the engine was breathing and stink from the fumes coming from the sump and it was using oil --we would be asked ""what the fuck did you do to it paddy ""
it emerged the English were correct and the engine should have lasted years more --HOWEVER we were supposed to put diesel into it----- but we got sub Saharan jungle juice from our cunt of a emergency oil refinery in cork which could only make HIGH SULFUR JUICE which burned 3 gallons of water for every gallon of diesel as thats how much moisture was in the air and when the water hit the high temp sulfur fumes it made sulfuric acid which destroyed engines .
except the engines of the state -bus eireann and the esb and the army were allowed to IMPORT REAL DIESEL LOW SULFUR .
The first station selling low sulfur diesel in Ireland was on the south circular near Harolds cross and all taxi-men would travel from north Dublin to fill each day until the public copped on and then there was murder and there were many court cases .
where the 3 gallons of water per gallon of diesel were mentioned .

this was caused by a pitot tube filling with ice .
this is a low tech tube the size of your finger on the outside and there is a small propeller spinning in the center and this tells the autopilot what speed you are doing .
the crew were all asleep as they regularly do on a transatlantic flight and both pilots woke to alarms ringing and the plane trying to fly but telling them it was stalling .
as the computer had read the speed had dropped to zero and it was desperately trying to fly it even though it was actually doing 600 MPH .
had the pilots been awake or even one pilot awake they would have spotted it but they could not judge their speed at 36,000 ft-they presumed they were stalling and they let the aircraft go out of control because they could not even look at the radar progression which would have told them it was not stalling .
they were still trying to cope with a bit of ice the size of an ice cube on a tiny propeller as they hit the sea .
thats why air France was successfully sued .
and i presume Boeing was sued also .

The fuel in Ireland is still well below the standard of the UK and much of Europe. Circle K premium is the only stuff that is worth buying but it's only as good as the standard juice in the UK yet costs an extra 8 cents a litre, another rip off.

Can't remember the details now but didn't something similar happen to a plane that had been laid up for a couple of weeks and an insect lodged itself in the pilot tube, think it was out in the far east though and the crash happened on take off, or shortly after.

That's right Sir. I remember watching the Air Crash Investigation episode on it (that was a great series).

It still doesn't explain why the Pilots pulled back on the stick instead of pitching the nose down to gain speed.

That's right Sir. I remember watching the Air Crash Investigation episode on it (that was a great series).

the auto pilot pitched the plane down to gain speed and the pilots pulled the stick back but the stall warning was blaring as the plane belived it was doing
0 MPH and the confusion was high speed but a stall warning and zero speed on the instruments .
you would have the trim tabs and the airlons trying to activate also to give lift when none was required .
most people do not understand why there is not at least 4 pitot tubes on any aircraft as they would not cost 50 euros each and you could take an avarage of the four or see that one was telling the truth 600 mph .
there are no mirrors for the piolets to observe the engines .
nor is there cctv for them to examine the control surfaces and engines on the aircraft .
a ordinary mechanic would design the plane very differently .

 

[Myles O'Reilly]

But if they believed they were stalling why did they pitch the nose up?

 

[BIG FAT HOOR]

But if they believed they were stalling why did they pitch the nose up?

When death is imminent and you have a nose down movement and with the altimeter showing the loss of thousands of feet they would pull back on the stick as their engine indacators would have shown full power .
the flaw is the blaring alarms stating zero speed and the stall warnings would be blaring also .
the pilots were overwhelmed with TOO MUCH WRONG INFO at the same time .
they were unable to compute reality as the aircraft is not allowed to tell them the truth when one sensor fails .
its incredible how insulated from reality a pilot is as at 36,000 ft -- he has no true horizon and everything has to obey the instruments as nighttime is a disaster without instrument flying as you have no reference to tell you what height or what direction you are travelling in .
put a pillowcase over your head and ask yourself if you were asked to fly right now how well would you do -- but this is close to nighttime flying .

High sulphur crude oil was a cheap feedstock, if the Irish were daft enough to buy it then the oil trade was happy enough to sell.it. Sulphur though, adds to the lubrication properties of diesel and now that it is removed older diesels will wear quicker unless additives are used to make up for the deficiency.

A short time ago approx 12 years when all farm machinery was by common rail computerised engines there was murder in the industry as some high performance tractors would not run on the jungle juice as the sensors in the exhaust said engine fucked please repair NOW NOW see your local dealer as the noxious gases overwhelmed the computer and no computer was told about the jungle juice --with no additives and no proper use of a fractioning tower .
where you can learn about diesel is in the RC world of flying scale model aircraft --these have races and the quality of the homemade diesel is the key --the 2 cc engines rev to an astonishing 14,000 revs and they produce vast power and the diesel contains castor oil and kerosene and ordinary road diesel and ether and nitro used to be allowed but the british army tightened up on anything which was a basic bomb material --so id say it fairly tame stuff today but it will tell you WHAT'S MISSING FROM THE JUNGLE JUICE .
The refinery is an emergency refinery --enough for the army guards fire engines and government ministers .
the diesel was relegated to heating oil only for a time until something was done and the tractor men had to put up with a bad situation for a while .

it might lubricate to a tiny degree in the injection pump but sulfuric acid does not lubricate the rings and valves .

The waters are a little muddy here I'm thinking.

Sulphur in the oil is indeed a lubricant, think EP90/80, however. when it reacts with the water in the oil, or condensation in the engine, then it can form sulphuric acid which is when the problems start.

A cairde, buiochas mor for the fascinating, mindblowing and informative comments on fuel. Superb comments.

But let's keep the thread focussed on what's in the skies. So unless it refers to fuel as used in planes and other things in the sky please post to general chat in the Marcus lounge. Or start a fuel thread.

Aris, thanks for the great quality comments.

Thank you, but echoes of the noughties here and the early days of fora where folk would insist that boundaries were rigoursly adhered to which made for a a much narrower view of the world.

 

[Diarmuid]

Ah, the good old noughties. God be with the days.

Saw a great trail in the skies t'other day as one of the only two honest cops left in ireland (his own description) was driving me home after an entire night's totally illegal detention in the cells.

Look, sez I to him. There's a trail right there.

It's condensation sez he.

The debate continues.

His buddy, the other honest cop, claimed that his own dad was killed by a massive clot after the vax. And he actually brought up the JQ of his own accord, a remarkably brave/insanely stupid thing to do.

Chemtrails, spraying for spraying's sake?

On my travels lately, here I was yesterday in the Picos de Europa in Asturias hiking. At 3000 ft where I was standing, I had a closer view of what they were doing. The three videos are a mini timelapse, maybe ten minutes apart. Watch how it morphs. This was 100% confirmation for me that these are not condensation trails.

Key points
This is a very VERY sparsely populated area, the nearest city is 100km away. Are they just dumping for the sake of it, run up the billable hours, empty the tanks?
Cloud descended 3 hours later at about 800 metres, total grey. It had been a beautiful sky blue, 25 degrees, just lovely. God's creation in all it's wonder.
Four different airlines involved, this is now the Airline business model as mentioned before, large and small carriers. Pilots MUST all know, yet none talk. Governments clearly sponsoring this. Happening everywhere. Everyone oblivious, Portugal seems to be a resupply area.

Why are they doing it? So many possibilities.

I can't click onto the images. But it seems he provides flight maps and numbers. Are they legitimate flights?

For lavish detail check out Dane Wiggington (no kidding, that's his actual name) on geoengineering.com. I would be very interested to hear your assessment of his info.

Lots of "roarers" today. From what BFH says, they must be military. There's no need for any plane to be flying low in these parts.

Well, I went to the site and tried to find some solid science behind his disbelief in contrails, but there was certainly nothing written, only demands that I watch various videos, and the one I started to view only repeated the text so I didn't bother going any further.

Engine exhaust is mainly water vapour and CO2, irrespective of whether it is a high bypass type or not.

 

[Mad as Fish]

Here is an interesting image from WW2.

Here you can see two distinct types of contrail being produced by the same plane, in this case B17s.

The first is condensation from the engine exhaust which are the fluffy white trails while the second are the spiral hoops which are propeller tip vortices caused by pressure drop as discussed before.

Are we to believe that the allies were as concerned about geoengineering the atmosphere as they were beating Germany and Japan? Out of all the crashed planes that have been recovered and restored there is no mention of extra equipment for spraying chemicals from the aircraft.

IF you take a vast amount of air which has in varying amounts ---rain which has ice crystals and condensate cloud and clear sky which also has moisture and you put it through a jet turbofan -
-the first stages of the engine are simply compressing the vast amount of air in order to raise its density in order to raise its oxygen content prior to injecting fuel into the compustion chamber which is simply a barrell surrounded by maybe 20 injectors which constantly spray the compressed air with fuel.
the entire process is self igniting and the ignitors/spark plugs are only used during start up as once the combustion chamber is lit there is a constant stream of air and fuel into the ignited chamber and that is why the engines give so little trouble as the concept is so simple .
the ignited mixture burns and leaves through the tail and gives thrust doing so.
the vast amount of air captured by the first fan is enough to capture any staff member mad enough to walk in front of it and suck him into the engine .
it would be very rare for air to be sterile of moisture over ireland and at 36,000 it is -80 degrees or colder and the wind chill from doing 600 knots is another factor which affects the wings and the black strip you see on the leading edge is a rubber bladder which pulses and breaks the ice on the leading edge and the 600 knot wind does the rest by removing the ice which is really water vapour .
if the ice gathers on the wing surface the aircraft crashes due to the weight and the change in areodynamics brought on by the change in wing shape with ice .
so water is constantly present in the engines .
and the problem you must face is if a single aircraft mechanic was asked to sign off on an aircraft with equipment fitted to an engine they were not familiar with or equally unsure of,
they would never sign off and the aircraft cannot fly .
the airlines have no control over staff at a foreign airport and their competitors would party for a year if they could show their rival airline was poisoning the world .
it is extremely unlikely any commercial airline would risk that --it would be a death sentence not to mention their insurance would be cancelled as there is no type approval for a poisoning aircraft in existence .

Big IF. Engines are your speciality. Info distribution is mine.

You can have all the proof in the world of some horrific crime, but showing it to the world is not a simple matter. If the PTB are protecting the airline doing the spraying, it is effectively zero risk for them. The airlines don't control staff at foreign airports. The PTB do, body and soul, barring the occasional brave whistleblower.

Yes, the principle of a jet engine is that simple, a ram jet is simpler still for it has no moving parts, other than pumps and ancillaries.

Geared turbofans especially, are incedible pieces of engineering for the main fan is geared down to run more slowly than the central shaft, how these are made to be so reliable is a wonder, to me anyway.

But I digress. To be half near to sympathy for your cause I really would like to know what they are spraying and at what rate to cause the contrails we see? At this point it should be pointed out that, according to your thinking, if the application rate is much the same then the contrails would hardly vary, but apparently a major plank of your reasoning is that they do vary enormously?

Old tech, why should that make a difference to physical effects?

Weather modification through releasing certain chemicals into the atmosphere kicked off in the 1950s using, if I recall correctly, compounds of silver. Without rushing off to check up the latest developments weather modification can be done but it is unreliable, if it was that easy to control then merely predicting the weather would be a cinch, but we all know it ain't.

Do you remember the tornado in Leitrim village, back when Varadkar was in charge? There was a blue flash of some kind. It tore the roof tiles off one half of a semi d house and left the other half completely untouched.

But the most suspicious thing about that tornado was that Prince Leo went out of his way to visit Leitrim village a day or two later. We all know that Leo doesn't give a fuck about irish people in general and Leitrim people in particular. Nobody was killed or even injured, so why bother? One plausible explanation was that he visited to gloat about the secret tornado weapon....

At the end of the day all jet and piston engines burn hydrocarbon fuels, and hydrocarbon fuels produce water and CO2 as a result of burning them, no matter what the engine design.

True. But

1. The vast majority of the time there is zero condensation trail, due to the design of modern engines.

2. Sometimes there is a tiny trail that disappears immediately.

3. Other times there is a huge big fluffy trail that widens into haze or cloud and is present for longer than a few seconds.

This third category is the mystery.
