That wouldn't have won the war.

Only problem is that your stone tower will collapse under its own weightYou know, if you think about it, you could have the Romans get to the Moon by laying stone end to end.
Just assume Hero of Alexandria's steam engine...

Has anyone figured out how to get the aeolipile Sealion Status yet?

Is is possible to rendevous with a passing spacecraft?
I'm thinking of Baxter's Voyage or something like it. Instead of sending the astronauts on a 2 year outbound flight the space craft is sent on a trajectory to get gravity boosts from Venus and another from Earth. As it approaches Earth a manned spacecraft docks with out out in cis-lunar (how close does a gravity boost trajectory come) and puts the astronauts on board. The people only have to do the last, double-gravity-assisted leg to Mars and then back.
I'd think that this would amerliorate a host of problems such as radiation exposure, supplies etc and the need to build a powerful rocket that would be needed to solve these problems. But is it possible to get a crew onto an empty spacecraft moving at interplanetary speeds?
