Remember it well
The Mitchells came into LTN and were painted in the old Court Line Tristar Hangar. I was a Liney at LTN and we used to push them out of the hangar when they were filming and put them back in at night. There were at least four if not five of them. Watched my copy til it wore out as well. 'Mitchells do fly in IMC' was the response given by a BY a/c to ATC over the south of England when advised to keep an eye open for the a/c inbound on the ferry flight.
