Vanilla Aircraft

The Vanilla Aircraft VA001 has broken the unmanned internal combustion powered flight record by staying aloft aloft for 5 days, 1 hour and 24 minutes. After flying in a circular orbit for over 7,000 miles, it touched down with three days of fuel still in its tanks.

A representative from the National Aeronautic Association has certified a non-stop, unrefueled 56-hour flight by Vanilla Aircraft's VA001 as the world's longest duration flight for a combustion-powered UAV weighing between 50 to 500 kg (110 to 1,102 lb).
