Not much mention on how they deal with aero drag.
"We should be able to extract some of the potential energy of the

So, dealing with aero drag by coming up with a rationale for treating it
as thrust instead. Neat trick!
Yes, I rather liked that one.
In another neat trick they treat propellant as ballast, so just throwing
it away makes you go faster - and using it as rocket fuel makes you go
fasterer twice over!!
It's only a wonder the ISp isn't even higher!
Shame they failed their science high school classes ...

Also, their "pending patent" for burning lift gas as fuel doesn't
exactly seem to be anything new ...
