With my fuel launcher idea I was accelerating the ship without using any
onboard fuel.  I need the 2,500,00 spec impuse so the ship could carry
enough braking fuel to stop from .3c.

Some kind of drag chut would be nice, if their was anything to drag against.

Yeah, we've all managed to chew up and spit out most all the ideas we've
come up with, and yes  I rtemember you realizing that the MARS drag motor
could overcome the microwave thrust from the rectenna.

I suppose on the bright side were not doing much worse than others.  Maklov
(sp) who wrote the starflight handbook was in a artical in Final Frounteir
magazine where he figured we launch thousand year solar sail ships to the
local starsystem in the next century.  (Only if we all go retarded!)
