"There but for the grace of God go I".........It happened to me in the North of Germany during manoeuvres with the Brit Army. A combination of poor weather and "gethomeitis" and very poor captaincy decision left me with a red, egg-covered face and a Gazelle parked in a field 1500 metres from my HLS. I landed with about 20Kg's of fuel on board. The boss sent a bowser out to me and you can imagine how popular I was with the boss and the lads on the bowser crew. The moral of the story is Planning, Planning and more Planning. Check points on route for groundspeed and fuel consumption are essential. The other thing to remember is "NEVER PASS GAS"(Meant in the nicest possible way). Diversion airfields at several points en-route should be planned and used, if necessary. A little embarassment is much better than being cold, stone dead!
Sorry, the answer to the question should be LAND and sort it out from there!!
