Have you noticed how all external shots of those hard at work EVA guys fixing whatever needs fixing whilst hovering over a lovely blue earth – these shots never ever show any sign of any jet trails? Go to flight tracker and look just how many aircraft are in the air at any one time, it’s literally 1000s. But no trails anywhere. It’s as if NASA has instructed the world’s airlines to stop flying while they film? I’ve reviewed about 10 space walks so far over a clear blue ‘globe’ and not a single jet stream. Ransomovitch
