I would be terrified to fly in a Lynx with Crab....he might want to turn the thing upside down with me in it (intentionally.....which makes me wonder about his sanity....and not his flying ability).
While flying the BO-105 and BK-117....with visions of Zimmerman and his aerial displays in mind.....I could never get up the courage to do a Roll or Loop in them.
We did have one Aircraft, an S-58T (very similar to Wessex)....while departing a Rig one dark and foggy night, encounter a bit of a problem and the Cabin Attendent reported having stood on the Cabin Ceiling for a bit....but that was not intentional on the Pilot's part.
