Another video highlighting different colours in contrails.
The video covers two dates during 2014.
24th May covered from 0:00 to 2:52.
25th May 2014 from 2:54 till end
Video description
Of course his claims are flawed when using the upper air readings.
24th May, 2014
Upper air readings from Sterling at 12 UTC (0800 Washington Time). He is making observations of the sky and filming at 1325 Washington Time (1725 UTC)
He is filming the skies some 5 hours after the upper air readings were taken.
25th May, 2014
Upper air readings from Sterling at 12 UTC (0800 Washington time). He is making observation of the sky and filming at 1525 Washington Time (1925 UTC).
He makes the claim at 8:05 in the video that the humidity levels are under 20%. Those readings were from Sterling at 12 UTC. The aircraft filmed on the 25th May were being recorded at 1925 UTC.
The interesting part for me was the different coloured contrails. He claims that he captured a pair of teams of two jets. He makes further claims that they are all at the same general altitude and that one of each pair did not appear on flight tracking software. Nothing unusual in that as not all flights are visible on such software. I believe that the first pair did appear on Plane Finder but he was fooled by perspective.


US721 US Airways Airbus A330 was flying at 40,000 feet and US1927 US Airways Boeing 757 was flying at 32,000 feet. From his filming location it would appear that the aircraft were flying in a pair. I believe that the 8,000 feet difference led him astray? The different colours are nothing but the contrails of two airliners at different heights reflecting the light differently.
