A suborbital flight, and repeat it with the same vehicle in a 14 day
period?

Funny, I can't remember hearing of such a thing.


The capability was there. Individual X-15s were flown within two week
periods a number of times and the craft was flown above 100 km.

So now it's not "it's already been done," it's "it *could* have been already
done?" I think it's time to give up. The X-15 was a really cool plane, but
it wouldn't qualify for the X-Prize even if it was operational today. It
couldn't carry passengers.

It's a shame the orbital followons weren't funded, or space travel would
have looked very different for the last forty years.
