Corrected entry: The hang gliding scene couldn't work because there is no way these people could fly these things. Flying a professionally designed glider takes several hours of training, yet these people manage to fly these home-made ones with great ease. (01:16:05)
Corrected entry: When Snake shoots the surgeon general with the dart there are two reasons why that wouldn't work - 1) There isn't any muscle tissue and the skin is too thin for the dart to stick most likely. 2) The tranquilizer would never take effect that quick unless it was injected into a muscle where the blood supply is greater. Intramuscular is the preferred method for fast-acting injections. (00:41:55)
Corrected entry: When surrounded by Cuervo's men, Snake calls for Bangkok Rules. He tosses up the can, shoots the guys down, and the can hits the ground. When it does, it rolls like a regular can, but then it rights itself and sits open end up. This defies the laws of physics. It was either pulled, set with magnets, or it was very bad CG. (00:34:45)
Corrected entry: It's never explained how it is that Cuervo can withstand a direct shot to the chest from Map to the Stars Eddy. He's not wearing a flak vest under his tanktop, and we're never given any reason to believe he has superhuman powers. For that matter, mere seconds after receiving a brutal boot to the head from Snake, how is he able to stand and fire a SAM anyway?
