Orbital velocity, however, is about 17,000 MPH, with the lowest orbit being about 100 miles up. The parking orbit for the Apollo lunar missions, before setting off for the moon, were at 107 to 119 miles altitude..
OK, and ... ? The item under discussion is a piece of steel that supposedly got launched vertically upward by and explosion at 25,000 mph (escape velocity).
Not too sure why orbital velocity is relevant.
