pontifex,
You must have delivered a Mk1/1A Victor to either Fred’s Sheds at Radlett or to St Athan for servicing with a four man crew.
I recall once having to return to Marham by train - immersionn suit and all- when the aircraft we four crew were due to pick up went sick. Also, on a separate occasion Marham had the good grace to send a couple of Canberras to pick us (4) up.
