Part of the challenge is to take enough fuel. If you're running out of fuel, load more before you roll. If you're still running out load a DT. If you're STILL running out -- well either you're flying for 2 hours or you're just not doing it right for most planes.
Part of the challenge of getting your name in lights IS to get back safely. Not to get back 10 feet from the field. Not to ditch in all but name, and have somebody cart some gas to you....
Let me ask you this: Would you still want this if as SOON as you loaded the gas it counted you as ditched, gave your kill to the last guy to shoot you, and computed the score then and there?
No, you would not. The ONLY reason you want this is because you're aiming for score.
P.S. I'm of the opinion most folks that screw around with light fuel -- i.e. 25% -- are taking their own individual gambles. If they gamble they can find a fight and get back before running out, it's THEIR FAULT if they lose that gamble. They shouldn't be rewarded for losing the gamble and running out of gas somewhere away from the field.
