A splendid programme.
My grandfather, a Sergeant Fitter at Odiham in the latter part of WW2, used to tell the tale of an ATA lady who delivered a new aircraft( possibly an Oxford?) to them from a factory "up north".
Upon landing, she stated that it had been "running rough" for the entire flight. On inspection, it transpired that the nuts securing the propellors were loose, and could be turned by hand!
Unperturbed by this event, the lady was soon on her way back to base, ready for her next assignment....
