Mysteries, Chemtrails, Aerosols :: Mysterious NZ

[Freedom]

Weather from the Wenderholme regional park this afternoon, hazy wispy blue sky out west while the sky overhead was a very deep clear blue. I noticed a contrail following a course up the western coast, then witnessed the trail stop and start several times befor the jet disppeared into cloud. The contrail evolved over half an hour into long narrow clouds and then after an hour the whole larger cloud mass became dark and heavy like rain cloud. I was amazed to see this and is my first experience of contrails first hand and also here in NZ. Very scary phenomenon.

Hi Freedom,

What time did you observe this? I was driving along Great North Road, going towards Avondale around 4.15pm and saw a persistent trail that stopped and started again like you describe.

It was at about 1600 and I observed the contrails until about 1700.

It must have been the same one. It was hard to get a good look from the direction I was driving but it looked like it stopped and then started 2-3 times. It wasn't a long trail, very thick and white and dispersed into a couple of blobby shaped clouds that were quite different from other cloud cover in the sky.

The only other time I've seen something like this was a few years ago over East Auckland going towards the waterfront. It was a cloudless summer evening and we came out of a friend's house to see two thick white trails (in stop/start fashion) across the sky. They just hung without dispersing in any hurry and certainly didn't look like any normal cloud formation. We didn't stay long enough to see what happened over the next hour or so. Pretty unusual stuff :?

I spent several years living in London in the early 90's and it was common to see contrails crossing the sky, but since living back in Auckland for the past decade I can only remember seeing contrails occasionally, and then usually only on cool clear winter days. They are more common further down the country because the aircraft have reached altitude, and one reason why we don't see many contrails or vapour trails in Auckland is because most if not all of the flights are either arriving or departing Auckland Airport and they are therefore not at altitude. Yesterdays possible chemtrail was left by an aircraft that appeared to be flying up the coast, possibly heading for Queensland. The day was warm and cloudy which isn't typical of a contrail day and appeared to be at a relatively low altitude. The key thing though and one confirmed by Carus is the contrail was switching on and off, if this trail was vapour from a jet engine, then the only way to stop the trail would be to stop the engine, that doesn't happen unless in an emergency. If any aircraft were to suffer engine failure over NZ, it would have made the headlines. Maybe this plane had two or three engine failures, or maybe it was part of a global perpetrated covert weather engineering conspiracy that has sadly now reached our sky's.

You're right Carus, temperature zones blend into each other rather than have cut points therefore a thinning off of the trail would be the prominent result. Hector's theory doesn't sit right with that one. His debunking effort was fascinating though.

I too noticed chems on the day you mentioned with dark clouds rolling in. The weather mod theory certainly seems convincing sometimes but for what purpose?

Hi Freedom,

Just to give you a bit of information about your comments above regarding jet engines being turned on/off in flight.

First off when you turn an engine off in flight it doesn’t stop spinning. There is always air passing through the engine which will result in the fan spinning. As you know, the contrail is formed by the reaction to the hot exhaust gases and (according to Hector the humidity and other things that are in more detail throughout this forum) The only way to shut down an engine in flight (remembering the engine will still be spinning, albeit at a lower speed) is to turn the fuel off. This is actually how you shut an engine down normally. The engine is designed to operate continuously regardless of any electrical faults or issues that might develop in flight.

I have actually seen a video of a 747 that ran off the end of a runway in Tahiti some 10 or more years ago and the nose of the aircraft ended up partially submerged in the water while the tail and fuselage stuck up in the air. The main electronics compartment is in the nose and this was underwater. Obviously this resulted in massive electrical outage and they couldn’t turn the engines off i.e. by closing the fuel valves which are controlled electrically. They called in a couple of fire trucks. The firemen pointed their hoses down the front end of the engines and then poured massive amounts of water into them to flame the engines out one by one.

To address your statement about the on/off effect we must look for some other cause because IMHO I just can’t see this being caused by engines being turned on and off.
As Carus has said above it could be atmospheric but I’m not siding with Hector on this either, I’m just staying open on it.
