Yesterday late evening on swedish radar I saw a B747 crusing on UN858 at FL430 :
It must have been an empty flight, because I have never seen a 747's flying so high.
Although, 747-400 is certified up to FL450, the highest cruising 747 I saw before was only FL400.
Hmm never thought about that before. I guess just for show, but its nice to see. I once spotted a BMI contrailing overhead London with the naked eye because they stand out so well.
Anyway about the equipment, I wonder if its got anything to do with the RAW format
Because I switched from JPG to RAW this weekend.
