The August issue of AOPA PILOT reports a "tiny jet engine" is being
developed with 150 lbs of thrust. Its 15" long, 8.6" in diameter and
weighs 19 lbs. I wonder what it costs? This sounds like a great power
to weight ratio.


It is, but what you gain from the engine you loose from the amount of fuel
yoo have to carry. Take a look at www.microjeteng.com for what's available
now. I seem to recollect that a video was published on the internet of a
glass glider with a pop out pod with two jets on it.
