Didn't take long to figure out this explosive tactic. You would think an airplane crash would do enough damage alone. But apparently in BF1943, to get the right amount of bang, you need to strap a demo charge to your plane and detonate it once you exit. In mid-air. Land safely and kill a few more baddies for some extra prestige.
If the game really had explosive planes, would people just kamikaze all the time? I think so.
