zilion thanks Flateric ;D

Yup. Thanks 1 0000000000000000000 times, that's fascinating!

What kind of booster did they planned for this thing ?

EDIT : 17 years later I attach the document, as the link is long dead (ding, dong, the link is dead !)

It would take a 200,000 pound, two-stages, non-LH2 booster (330 second isp) to orbit 10,000 pounds. A B-52 can't carry that much, but a C-5 or a 747 could. They picked that weight range because of DynaSoar, but Gemini would be a much better bargain.

Fun fact: the paper discuss 320 and 335 seconds specific impulses; but nobody thought about mixing Titan I oxidizer (LOX) with Titan II fuel (hydrazine), into an hybrid LR-87 or LR-91.
That mix has a very energetic specific impulse, in the 360 seconds range.
