I know of one guy who landed out at another airport, had lunch, got a tow
from their operation, then landed back at home field. Stated it was one
flight and full duration. Only after flying at the other operation did I
learn of his visit.
lol. I thought that was what barographs were for? Or did I miss something?
Mind you I recall back in the 70s some guy (from the UK I'm sorry to say)
who faked a record height climb by swopping baros after he landed. Got
found out eventually - he was too greedy.
