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 andthermocouples on P&W jet engine turbine blades. It was for real timetesting of turbine blade designs.I visited the P&W facility in Florida after the system was deliveredand installed and was given a plant tour. One room had a number ofpeople seated at tables who were physically handling turbine bladesfrom 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.===Interesting, and a bit counter intuitive. How do you get anelectrical connection to a strain gauge that is rotating at highspeed?

I told you he's smart.
