+ | I was on a plane flying near mt Everest. | ||
+ | 11:14:58 From Steve Isenberg to Everyone: | ||
+ | The pilot would apply some changes to the airplane’s controls automatically to maintain level flight. | ||
+ | 11:15:25 From Bob Primak to Everyone: | ||
+ | Problem is that the angle from which the sun is shining (Azimuth) is at a somewhat inconvenient angle compared to flight path. From the plane’s view the sun (and thus eclipse) would be about 7 or 8 o clock when looking at a clockface. Therefore the best would be that when totality shadow starts (or right before), the plane flies in a more northern direction or even a bit northeastern so most people on board would be able to see it clearly since we would then be at a right angle towards the eclipse (9 of clock). But this requires either that the pilot is a bit flexible (like the SW pilot in 2023 who did some zig zags as spur of the moment) or needs proper flight path planning which is what Alaska airlines did. | ||
+ | 11:16:20 From Bob Primak to Everyone: | ||
+ | In this flight path, the pilot does some zig-zags to let passengers on either side of the plane to have a view. | ||
+ | 11:16:34 From tedpk to Everyone: | ||
+ | Airliner should get you above most of the clouds -- so it could be useful -- the SR-71 once flew along the path of totality fast enough to "make time stand still" by doubling the length of totality | ||
