The original velocity posted 14 Nov 2001 didn't have either feet per second or meters per second, just " Velocity: 27,875 kph (17,321 mph)", numbers which remained until Dink87522's edit.  So the 7,643 should have been 7,743, and it was here that way by the time this was split from Space Shuttle Program.  That 27,875 km/h = 7743+ m/s = 25,404 ft/s, but probably not to that precision.
