- The conclusion of Machine Gun Jetpack.
- This bit from footnote 5 of Falling with Helium:
Additionally, while researching impact speeds for this article, I came across a discussion on the Straight Dope Message Boards about survivable fall heights. One poster compared a fall from height to being hit by a bus. Another user, a medical examiner, replied that this was a bad comparison:"When hit by a car, the vast majority of people are not run over; they are run under. The lower legs break, sending them into the air. They usually strike the hood of the car, often with the back of the head impacting the windshield, "starring" the windshield, possibly leaving a few hairs in the glass. They then go over the top of the car. They are still alive, although with broken legs, and maybe with head pain from the nonfatal windshield impact. They die when they hit the ground. They die from head injury."The lesson: Don't mess with medical examiners. They're apparently pretty hardcore.
