i disagree, the planes in your video are those types that always have that trail behind them, those old planes do that normally, and probably even
used a different fuel, and definitely had very different engines.
i can tell the difference between a contrail and a chemtrail.
chemtrails linger, contrails fade away much faster.
Do they always have the 'trail' behind them. Really? Would you care to go onto an professional aviation forum such as PPRuNe or an aviation enthusiast
forum and make that claim? Are you sure that it has nothing to do with the altitude or the atmospheric conditions at height? in your world these old
planes just do that normally. There are still a good few WW2 aviators around. Explain to me why none of the WW2 aviators will agree with you that
their aircraft always produced a 'trail'. Explain to me why ground observers didn't notice your version of events during WW2?
See link posted and note the observations in Flight Magazine from 1939 onwards. The increase in aviation during the build-up and period of WW2 brought
about an obvious marked increase in the observation of contrails; both persistent and non-persistent. Follow the timeline at the links posted and see
that persistent contrails didn't suddenly appear in the late 1990s.
Explain to me why test pilots didn't note this trail that you are suggesting was always there?
Geoffrey de Havilland, Jr, test pilot, wrote in Flight Magazine in June 1942
VAPOUR TRAILS Views of Well-known Test Pilot I WISH to correct the various erroneous statements that have appeared in the correspondence columns
of Flight concerning the origin of aircraft vapour trails. The trails referred to are, without doubt, due to the condensation of the water vapour
content of the engine exhaust gases; this condensation will always occur under favourable conditions of humidity and temperature at high altitudes. I
have myself frequently observed these trails from the cockpit of a high-flying aircraft in the very act of formation at the exit of the exhaust pipes.
The formation of a short trail, or, as Mr. Dixon has expressed if, a trail "like the wake of a boat," is merely the prelude to the formation of the
familiar "permanent" condensation trail which will occur when the aircraft in question runs into more favourable atmospheric conditions. Another type
of trail which may be induced by the passage of an aircraft through air of high relative humidity may well be termed an " adiabatic trail," since it
has its derivation in the adiabatic cooling of the air concerned to below its dew point

Full timeline at following links.
P-51 Mustangs producing contrails. In your world they have nothing to do with favourable conditions of humidity and temperature at high altitudes? In
your world they would still be producing the trails at 10,000 feet?
P-51 Mustangs escorting B-29s. Why are there no 'trails'? In your version of events they should be producing a trail.
Footage of B-17 and fighters. Note contrails and periods of none forming. Surely in your world they would be leaving a trail at all altitudes?
Note at 01:16 the B-17s. Note the B-17 producing no contrails while the B-17s at higher altitude producing contrails? Conditions for those higher
B-17s are favourable for the production of contrails. If the B-17 was to climb up to that formation then it would be producing contrails.
Is it beginning to set in that your interpretation of 'trails' is flawed?
