Hello everyone) Question: Has anyone flown on an airplane, say, "in a position?" How was your condition during the flight? In two weeks I'm moving to another city, and my doctor said nothing about the flight. "If the stomach is very visible, you won't be allowed. Any certificates are not given. You want to fly, you don't want to fly" And by train 40 hours - that's something ?
