Spent 160 hours aloft from Japan to just off coast of Baja Mexico.
Is it still a record if you splash into the water? Maybe balloon records are different, but in the airplane category, I think you must land at a real airport.
Interesting side note: FAI regulations state that the pilot must be alive for one day after the record attempt / flight. Eliminates the possibility of someone crash landing at the end the flight but still claiming the record.
