Good luck and don't forget your parachute. Sheesh.

Since Boeing doesn't make engines and the Pratt and Whitney PW4000 is
used on Airbus, and McDonald Douglas planes too, maybe you better take
the train.


Right...the loonytarian response...Boeing doesn't make the engines, so
it isn't responsible.


What failed? Boeing didn't make that engine, they come in assembled
and installed as a FRU
Perhaps you should be blaming United airlines for sloppy inspections.

The engine was made by Pratt and Whitney, as are about 9% of the other
Boeing 777s. The other engines are made by Rolls Royce and GE, and
are not known to have any issues. Supposedly the FAA sactioned Pratt
and Whitney a few years back for not providing their engine inspectors
with sufficient training.

The good news is that the plane landed OK and no one on the ground was
injured. There were some pretty big chunks that fell on those houses.



Many years ago (back in the early 80's) I was involved with the design
of a vacuum deposition system that deposited thin film strain gauges and
thermocouples on P&W jet engine turbine blades. It was for real time
testing of turbine blade designs.

I visited the P&W facility in Florida after the system was delivered
and installed and was given a plant tour. One room had a number of
people seated at tables who were physically handling turbine blades
from bins at each table.

My host explained that they were all visually handicapped or blind and
were using their sensitized sense of feel to inspect the blades, feeling
them for inclusions or other irregularities in the blade surfaces.
