Lemain, if you read back through the thread you will find an instance where the pilot did exactly that which is why suicide is a discussion item.
Then the question of minimum runway length for take-off obviously depends AUW of which fuel load is the major variable. To assume it needs a full fuel load to reach a distant target assumes that the target is indeed distant. It might also be conceivable that any plan could be for a short field, light load take-off followed by a brief stop at a compliant larger airfield for refuelling.
Personally I think that is a nonsense and I suspect the aircraft crashed or ditched.
