Debunked-Peter Kusznir "Military Learjet" video

Peter Kusznir posted a YouTube video this week purporting to show a "Military" Learjet allegedly "chemtrailing" over Melbourne Australia on Tuesday 10 June 2014.


Kusznir also videoed the QF63/64 flights that were flying between Sydney and Johannesburg.

The Flightaware website revealed that the Learjet was a LJ36, a longer range version of the Lear 35 that was flying between Invercargill in New Zealand and Adelaide in South Australia. The registration was N41GJ and was registered to a company called Maritime Sales and Leasing which is based in Newnan, Georgia, USA and operates as Globaljet, a biz jet sales and leasing company. The Learjet was not military.

Analysis: "Earth" page for Kusznirs' location and time reveals a saturated atmosphere at the 250mb level.

The MSL pressure analysis also reveals a cold front in the Great Australian Bight. These are classic contrail producing conditions. Kusznirs video also shows the normal pre-frontal cirrus cloud expected to be evident in these conditions.

Kusznir expresses surprise over the size and length of the trail, opining that this was "proof" that even a small aircraft can "chemtrail".

The LJ 36 is similar in size to the Sabreliner aircraft used by the Knollenberg study in 1972. This study proved that a persistent contrail from such an aircraft contained ice weighing between 21kg and 41kg per flight metre. This Learjet was flying at a rate of approximately 7.2 nautical miles per minute which would ultimately generate an average of 42 tonnes of ice per minute as the contrail persists.

A LJ 36A has a maximum weight of 8.3 tonnes.

Conclusions:

a. The Learjet was a biz jet operated by a US company that specialises in lease and sales of such aircraft. It was not military and identifiable at all times.

b. The Learjet and the two 747's were flying in conditions that were visually and measurably identifiable as amenable to the production of persistent contrails.

c. The weight of the contrail produced by an aircraft the size of a Learjet have been scientifically measured. By applying those findings, the Learjet would, in the conditions present, have taken slightly under 6 seconds to produce a contrail weighing more than the entire aircraft.

For the Learjet to produce a trail as optically dense as the one filmed, made up of material with an average specific gravity of 4.0 (AL2O3, Barium, Strontium etc) is not physically possible. The aircraft would have weighed far in excess of its maximum takeoff weight and would have crashed on takeoff at Invercargill.

Debunked.

Let me add to this discussion. First off, I am one of the pilots for 41GJ, we are not GlobalJet, we are Global JetCare, and from New Zealand we were flying a patient for medical transport. This Lear 36 carries 8100 lbs of fuel, 3000 of which can be jettisoned in case of emergency to improve stability of the aircraft and lower its weight to close to or under the landing weight. During no portion of this flight did we jettison any fuel. For combustion to happen properly the fuel (Jet A1) added with oxidizer yields CO2 and Water ref. http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19910021867.pdf

Typically at 0 degrees C or lower, that water will go from very hot in the combustion chamber to cold and frozen in the atmosphere. (Standard temperature at 40,000ft -65C) That's all there is to it. Water freezing. Feel free to look me up, I'm an employee of Global Jetcare.

Thanks Jon! I think this is the first time one of the pilots of the actual plane in question has chimed in :) (we do a lot of "what's that plane" stuff here).

Minor point with your explanation there - while water normally freezes at 0°C, contrails form around 40°C (as there's very few ice nuclei in the exhaust as it is very pure water and soot is not a good ice nucleus, so the water needs to fall below the homogeneous freezing temp at that pressure). Obviously still below the -65C, but I just wanted to make the point that it won't automatically freeze below 0°C.

Very true! However we are forcing the water through very high pressure compressors and turbines, just like water vapor reaching a dew point it will form a cloud of liquid water rather than frozen :)

I agree. It is time that all pilots become proactive in dispelling the fear generated by the chemtrails hoax.
Your life may some day be in the balance as chemtrails activism moves into chemtrails extremism and closer towards chemtrails terrorism;

Great video. I have to admit, a couple months back I took a break from reading the thread regarding threats against debunkers and aircrew since I was getting so enraged reading not only the threats from these misinformed conspiracy theorists, but from the people running those websites that incite and encourage such behavior.
