Wasn't it Double Top '81 when the USAF Bomb/Nav shop got their sums wrong on one of the targets and caused ALL their Buff crews to drop their bombs in a 50 foot bucket some miles in error? IMMSMR the bombardiers said that they didn't check the offsets on the grounds that they couldn't change them anyway............
The Farnboro "where's the destination" incident reminds me of the time when a group of us got a lift back to the UK from the USA in a USAF KC135. The newly qualified Navigatrix found recovering to a non-TACAN equipped base something of a challenge but didn't let that stop her trying to route us thru an active DA en-route!
We've all made mistakes but missing Farnborough takes the biscuit.
