Nice attempt at forging an email from me, but you aren't very good at it.

Well...the Electras that I flew certainly had "jet" engines.
Even burned kerosene. :-)

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

Bob has remarkable consistency in posting incisive, telling stuff,
gleaned without doubt over years of flying. Notwithstanding that, don't
you think your invective isn't quite apropos for one past 70?

When he wrote jet under two quotation marks, it was obvious he wasn't
referring to the obvious.

Just my 0.02,

The ones I flew had jet turbine engines but they were geared to propellors
which makes a difference. They are generally referred to as turboprops
whereas the term jet normally refers to a jet engine without external
propellors. But the difference is decreasing since most high-bypass jet
engines now have internal rotors which produce more than half the thrust
using propellor type action but within the engine frame. That air doesn't
even go through the combutions chambers, it bypasses them, hence the term
high-bypass.

But you knew that, Bob, I just mentioned it for those who didn't.

Way back, I believe the first jet passenger jet was the Lockheed Electra.

The first jet airliner was the de Havilland Comet. The Lockheed Electra
you're referring to was a turboprop.

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??? :-)

I'll use your post to add my comments on Electra.

Lockheed fixed the wing problem but bird had the bad name and airlines
didn't want to fly it.

USN bought a bunch (of the fixed birds) and put MAD gear and other
anti sub equipment in and have been flying them for years without any
wing problems.

Due to age and hours, Navy is starting to look at newer birds for
their mission. One being looked at is the 737.

correctly, the conclusion was that the wing spar failed from fatigue
because the wing was nutating, a slight circular motion due to
gyroscopic effects.

To jog your memory:

Maybe that's the same thing caused the FL seaplane crash.

The Electra problem happened pretty soon after they came out. Those
seaplanes have been around a long time.

The still derive significant thrust from the exhaust jet, but I'll grant
you that it is getting much grayer as the bypass ratios keep increasing.
:-)

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

Sounds like you're confusing it with the DeHaviland Comet. The cause was
eventually determined to be the rapid formation of stress cracks around the
corners of the rectangular cabin windows.

Coffee is only a way of stealing time that should by rights belong to
your slightly older self.

They also used a high pressure sea level cabin, modern
pressurized aircraft use a lower differential pressure,
maybe 8-9 PSI for a 9,000 foot cabin at max cruise altitude.
The Comet was a victim of design, fabrication and
operational methods.
