And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Skydiver Felix Baumgartner breaking the sound barrier
Felix is a stud.
ReplyDeleteI thought the maximum attainable velocity by acceleration due to gravity, aka Terminal Velocity, was 120 mph.
ReplyDeleteI think you're right. This is simply a shock wave with moisture rich air - but it's still cool.
DeleteOr a photoshop job?
DeleteI'm skeptical. Who took the picture? Looks remarkably like the cone from a picture of an F-14 I've seen.
DeleteIFRC the speed will be effected by the density of the air. The higher up the faster you go, till air thickens up and "slows" you down to 120MPH.
ReplyDeleteApparently he hit Mach 1.24, link above, which I should have put in in the first place (sorry).
