Following on from Fortissimo and TT's earlier posts - and apologies for a spot of thread/navigational drift - but not long afterwards, a 43 Sqn crew fell into a similar trap to the unfortunate Tremblers QRA crew. Well out of TACAN range and with only the hamster-driven air position indicator (on a good day it had a 50% chance of telling you correctly which hemisphere you were in) to rely on, the chaps began their RTB to Leuchars only to find upon turning south east that someone had pinched Scotland.
A PAN, quickly updated to MAYDAY later and our trusty crew, with only fumes in the tanks, landed in... ahem, Denmark (Karup, I think). Names of the guilty redacted to save embarrassment!
And just as a PS to TT's post, a clean F4 holds 13,200 lbs of fuel, so even allowing for the burn rate while tanking, taking on 14,000 lbs shows how close the Tremblers ac was to the hasn't-it-all-gone-quiet stage.
