At 86 seconds prior to landing the orbiter is at 425 miles per hour and at 13,000 feet; at this point the autoland sequence begins. Approaching the runway from this altitude, the shuttle has a 22º glide slope and a rate of descent approaching 22,000 feet per minute. Wow. That bears repeating, right there. A brick with wings, indeed. 13,000 feet in 86 seconds, that's an E-ticket Space Mountain elevator ride.

Care to dumb that down for those of us who can't comprehend speeds like that, and don't understand avionics?
