I recall being told by one of my Hunter QFIs that back when he was on his first squadron, the Meteor 8 wasn't long out of service. When the Hunters were grounded by snow, it wasn't unknown for some joker to ask around the crewroom "Do any of you chaps have any Meteor time?". Those who weren't wise to this gotcha would say "Yes" - only to be invited to man the MRD with its double Derwents!
