How bout this
Boeing the company I work for has teamed up with FORD the company that
makes the best vehicles, has made a simulated airplane flight using a jet
engine powered by hydrogen that lasted for three days (vnunet.com) is were
the story is. HMMM Boeing with the help of Fords hydrogen tech on a couple
of there cars good.

Okay so you really know what I meen,
But jet engines come in all types, and when speaking of JET it's refering to the airframe, the engine can be of piston power or turbin type.

Jets come in axial flow or radial flow. A "jet" powered by a piston engine is a ducted fan. Otherwise, a piston engine is a piston-prop design. A "jet" driving a prop is a turboprop.
Axial flow jets are what is used today, with all the little blades down a common shaft, and a big inlet fan. These are also referred to as turbofan engines. More can be found here:

Radial flow engines have never been used with any real success in jet aircraft, but are used in smaller applications. These resemble a turbo with the inlet side feeding the exhaust side, with an injector putting fuel into the airstream.
Here's an interesting setup with a jet engine driving a counter rotating prop:

And a video of it in action:

The sound is unbelievable, it sounds like a wildly built piston engine running wide open even when the engines are wound down for landing.

If it's a lesson your trying to teach me, don't bother, i am a Jet engine (of all types)
mechanic. My point, while I may have phrased it wrong ,was that Boeing with the
help of FORD MOTOR COMPANY are teaming up to develope an aircraft engine whether
it be a Suck-n-blow J41 ,J79 from a F4, turbofan TF34,TF30 from a F14, or a turboprop J56 from aE2, E2c hawkeye, that will run on hydrogen or powered by it. sorry forgot to say that this is a start to maybe powering the engines on
any one of boeings airplanes. starting with the simple design of an automobile
engine,
