737 thinks it's a DC-10?

exhaust down the intake of rear fighter spun the engine up to start
RPM and it was started and both flew away.

How did they keep engine temperatures within acceptable limits?

flawed logic: one would demonstrate the airplane's saftey by reduing
the thrust on a critical engine, and one offering off centerline
thrust would be the logical choice,

Hmm ... granted. I don't know that they waited until rotation to pull back
the throttle, though (it has been many years since I read about this). The
727 supposedly had a reputation for having plenty of power to spare, at least
compared to its contemporaries.

Of course, if it is the center engine that is INOP, then of course
it can be done at a light weight and a long runway.

I don't know which engine they idled, but logically one would expect the
center engine.

"Logically", you wouldnt argue with people who fly these for a living.
I thought it was clear that you cannot operate a 727 or any other
plane for hire if it cannot fly off the runway after losing an engine.

You're an idiot.

No it dind't, fjukkwit.

How would you know, idiot? We routinely did V1 cuts in all sorts of
airplanes when it was still being done. Not as demos but as routine
training.

Fjukkwit.

This is called a V1 cut and it is done on every sim check on every
crew for every plane flown in the world. The regs require the planes
weight to be limited so the plane can either stop on the remaining
runway if the engine fails before V1 or continue (and climout) if the
engine fails after V1.

The important point is that the aircraft still took off successfully
with one engine set to idle. Therefore it can take off with only two
of three engines providing thrust.


No it isn't mr backpedaler.

That's what happened to the El Al 747 in 1992 over Amsterdam. I saw
the "Seconds from Disaster" show recently that chronicled the
investigation. The #3 engine departed the wing and took #4 with it
(and 30ft of the leading edge) Incredibly, the captain was able to
recover the airplane, but when he slowed to make an emergency landing
the wing lost lift and combined with its high drag caused the plane to
roll right and it went in.

BTW, what th' hell is a bunyip??


You misspelled it. It is buttnip. Make more sense now? :-)

I don't think they were demonstrating safety so much as power in reserve.

I might. Sometimes the ones who fly them for a living crash into mountains,
which implies that they don't know as much as they might think. I don't trust
anyone who hasn't personally demonstrated to me that he knows what he is
talking about, and credentials don't count. Sure, most professional pilots
usually know what they are talking about in the domains with which they are
familiar, but I never take that for granted.

Yes.
