As anyone whos been skydiving will know, youve got to take your safety very seriously. A human being can die from a fall after just one storey if they fall in the wrong way, so when youre cresting the air in a plane and are going to jump out, a parachute is always called for. Unless, of course, youre Tony Stark. Lets set the scene Tonys been kidnapped by the terrorist group the Ten Rings and forced to develop missiles. In what turned out to be one of the most audacious and ridiculous bluffs in recent memory, he actually builds a not-at-all-similar-looking iron suit and massacres everything. He then flies away before it all goes balls-up pretty darn quickly Tony plummets to Earth in a powered descent before slamming into a sand dune at a good speed. Yet strangely, though the suit is pulverised Tony is remarkably ok, with no major injuries of any kind. Granted, hes not as high up as a skydiver, but hes definitely going faster than terminal velocity remember, until moments ago he was catapulting around in a giant suit so when he smacks into the sand, hes surely in for a world of pain. After all, his suits been smashed to bits, implying a hell of a lot of force. Yet hes curiously unharmed, and for no good reason. You cant tell me there were fail-safes in that suit, because its totally primitive, and it suffers damage everywhere. Yet when we see Tony again, hes got his arm in a cursory sling, - implying injury but hes still walking around. Ive got to ask how the hell is this possible? If Tony hadnt been turned into paste by the crash, he would most certainly be in a wheelchair, yet he later refuses one. Its completely bonkers, is what I'm saying.
