[QUOTE="sweller"] Rearward facing. Military aircraft apparently have passenger seats rearward facing because of improved survivability in the event of a crash. Trains, sit with your 'back to the engine'. [/QUOTE] The advantages of that position are fairly obvious, but I've always though that the benefits are offset by the person in the forward-facing seat opposite flying into me with similar force. The old seatbelt ad with the elephant charging through the windscreen comes to mind.
