Anyway, here’s my physics thought of the week for last week: $$v = \sqrt{2gh}$$. That’s the formula for the vertical velocity you need to reach a certain height as a ballistic projectile. To get 150 feet of altitude requires $$\unit{47}{\mileperhour}$$, and that’s if you launch straight up. Coming off an angled ramp, as they did in the show, you’d have to be going even faster. Of course, the guy in the myth isn’t quite a ballistic projectile; he gets an extended boost from the rockets. But still, $$\unit{150}{\foot}$$ of altitude is pushing it, so I would have been inclined (pun? intended? nah) to dismiss this one on that basis alone.
