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
