want to space. go to there. me, preferably now. build big machine. several large problems. can't breathe there. very far away. must fly fast. no air there.

- fuel tanks heavy. far too heavy. we drop them. drop when empty. solves heavy problem.

- gas in air. we breathe "oxygen". take with us. good seals important. solves breath problem.

- very far away. need big machine. small weight added. machine much bigger. take less weight. else can't build.

- no air there. can't use propellor. can't use wings. must use rocket. engines get hot. cool with fuel. dangerous but effective. build complex pipes. solves cooling problem.

- must fly fast. air slows machine. it's called drag. speed increases drag. must reduce drag. make machine pointy. much less drag. solves speed problem.

now problems solved. you come with?
