Not Hughes, but...
My old colleague Pat Tobin had been a F/E on TWA Connies. He told of a captain who was tasked (with crew) to ferry a ship from Kansas City Muni to the Fairfax maintenance base across the river. He grew tired of waiting for the other two to appear, so he started up the 3350s from the F/E panel, set flaps, moved to the LH seat, and flew across the river solo, gear down. Big deal, he got 30 days vacation for the transgression.
