Not so fast, fastener. What usually happens is nav/WSO confuses himself with a wealth of navaids in the back such as radar, INAS, GPS, Decca, Tacan, DME, Oboe, sextants and celestial charts and directs pilot into the bundu in completely the wrong direction. Pilot slides crumpled map out of pocket and has a crafty squint, nudges stick over a bit, adjusts speed a tad and says, 'Yep, on track as usual, nav.'
Seen it a million times!!!
Mind you, there are so many ex-Bomber Command airfields in the UK that anyone is bound to bump into some of them regardless of their navigational skills!
