And I did a slatless ferry once. Complete non event except that the nose down climbout attitude was a bit disconcerting. Captains used to practice a flapless and a slatless landing as a BTR (Basic Training Requirement) every 6 months IIRC.
Flapless landings were relatively common. If you got one of the wing hoses stuck out, you landed flapless to prevent the hose bashing the flap and damaging it on touchdown. I seem to remember that the 6 month flapless requirement was usually met with real events.
Don't think it's a Newfie thing Mr B, but probably due to moose attacks - my ferry was from Goose!
