Gee, Bob, you should know the difference between a turbine
engine used as a propjet from one used as a pure jet. :-)


Hey! Eastern Airlines called them "Prop Jets".
By the definitions posted here, there are no "Jet" airliners
currently flying, since they are all "Turbo Fans". Right??? :-)

The still derive significant thrust from the exhaust jet, but I'll grant

Then again, if it was black and white, what would we have to argue about
here? Things would get dull in a hurry.
