Hey Corky,

Forget about the engine, just add a large pipe to your mouth and jet that
out the back of the aircraft. There's so much hot air coming out, you
should break the sound barrier. The amount of thrust created by this affect
will be negligible at best. Get out your thermodynamics book and see for
yourself.

Gee Stan that was a bit harsh I thought Corkys plan was food for a good
conversation. Would have been more interesting if you explained why you think it
wouldn't work rather than a snippy remark. Just a little constructive
criticism not a bash.

See ya
