I guess we all know
this isn't gonna fix things,
1:28:06
uh, at least not for long.
1:28:09
We know you did
what you could for us.

[ Homer ] When the rocket propellant
burns, it produces a river of gas...
1:29:23
which flows through
the convergent section of the nozzle.
1:29:25

1:29:30
that is to say, less than
the speed of sound--
1:29:32
it becomes compact in the--
compacted in the divergent section,
1:29:36
bound in turmoil
and inefficient.
