Ball Bearing run
My late father - Jimmy Miller - was an R/O on the run from Leuchars. He flew many times with Nigel Pelly . I have found a load of correspondence between him and the Museum of Aviation in Winnipeg who were researching the flights. I have been in contact with the BA Museum and they are very interested in having it all.
He once told me they never carried a single ball bearing - it was mainly people and documents. Incidentally he was very friendly (after the war )with one of the German crew who were in Stockholm at the same time . The crews used to drink coffee in the same room .
