The idea for FSO is historical operation setup. That includes rides, strength and target. The P-47 without DT is accurate because RL jugs in early ETO would have used fuel in DT before they get over Germany.
Was it also historically accurate that 9 of 10 didn't make it back due to having run out of fuel?
I get the idea, but this is also a game, and to disenfranchise a large number of players making them fly 400 miles, with 380 miles of fuel doesn't seem to me to be the best path to FSO excitement. Your mileage may very.
