Actually he makes a point, when a ton of Aircraft ,fuel, and ammo run into say a field ack, something has to give. A single 20mm cannon round exploding will kill that ack. Yet a 2000 lb plane impacting at 200 mph plus won't? Granted thats ALL it should kill, ie single city buidling, single ack. What it should actually do is start a 2 min fireball 20 yards in diameter leaving a pile of twisted wreckage in the center.
Pearl Harbour I think said it best, "so your hit, not NOT going home, you can't make it, choice is to be captured, or take something out as you go"
Same holds true here.
Would it be abused, probably, which is prob why we havn't seen it.
