well i was 17 and I ran out of gas and landed in a field. Even though the gas guage wasn't reading zero which should have got me off automatically and I had a flight instructor at the flight school check my planning and said it was fine. Turns out the 152 was burning something like 10 gal an hr which is more like a 172. I know the POH doesn't tell the truth but the POH said about half that at cruise. Well i was young and obviously didn't know what the hell was going on so I just wanted it to all go away as quickly as possible. At least my emergency landing was solid .
