Applied Aerodynamics: Wake Turbulence and Contrailsby B74AComment by B74A: Thank you for all the comments.
This entry did a lot worse than I thought. Some thought it was taken with a powerful zoom from the ground (?), but it is taken inflight, as traffic is passing above. When two jet aircraft are passing head on (at different levels, preferrably!), it takes about 3 seconds for each mile you are losing in. Add to that the difficulty of focussing through the thick and multilayered windscreen, and it is somewhat a challenge to get it sharp. The sky is very clean blue aloft, so although I tried to adjust color and contrast, it is not far from what it looks like for real. I used to fly Learjets, and have been up to 48000 feet on one occasion. Besides being very clear from here that the Earth is round, the blue in the sky gets darker and darker, as one is almost at the edge of space here (not much more than 10-15% left here of the mass of the Atmosphere). |
