I thought that they were reffering to both forward velocities.
But, even with an impact speed of 700 MPH the force would be 790.5 tons.

Thank you. I figured I was splitting hairs anyway.

The youngest FReepers will be telling their grand children 50 years from now how they saw the last Shuttle, with an EFT covered in styro-foam, lift off in Jan of 2003. Whatever we see go into space from hear on out will not look the same. IMO.
