The only other reference I can recall is on p. 23, left side, Recommended 
DR, first paragraph (paraphrased): [...] ships designed to survive reentry 
should have DR100+.

Other rules that may apply:
VE159:
a vehicle that does not have Superior SL or better must make a HT roll at -1 
per 50mph over 650mph, or take 1d dmg/TON


There's also the section on "Loss of Control in the Air" p. 151

perhaps you could rule that the body takes damage in HP by the degree of 
failure?
