occam's razor suggesting shoddy workmanship would be applicable if it were only the vertical stabilizer that fell off. But, with both engines falling off as well, I believe that occam's razor would suggest something a little more intentional.

>>haven't heard of wind shear lately<< The FAA took steps to deal it... jsc.nasa.gov One of those accidents occurred at Dallas-Fort Worth Airport on August 2,1985, when a powerful microburst caused the crash of a Delta Airlines Lockheed L-1011 jetliner with 137 fatalities. That accident triggered a Congressional mandate to the FAA to initiate a research/training effort toward curbing the windshear hazard. In 1986, the FAA and NASA launched a joint program to develop the essential technology for detecting and avoiding microbursts. The FAA undertook an aircrew training program that focused on windshear recognition and procedures for recovering from its effects. FAA also led the development of ground-based windshear detection instruments, including the Terminal Doppler Weather Radar (TDWR) now being installed at 45 major U.S. airports; developed by Raytheon Corporation, the TDWR can accurately measure wind velocities in terminal areas and generate real-time aircraft hazard displays that are updated every minute.

Sudden wind shear problems while landing I understand. "Turbulence" in the case of the link below is where my complaint is. Now, if some one knows better then me (specially if they are in the industry and knowledgeable) by all means batter in with sarcasm, wit, and what ever else is needed to reassure the public that I am just some armchair nutball who knows nothing. To be honest I could stand that kind of humor. btw. I do understand rare events. If you have one million take offs and landings, you should not be surprised to see a one in a million type problem occurring. ====================================================== Despite a lack of hard physical evidence, the NTSB said last week that uncommanded rudder movement was the probable cause for the fatal crashes of United Flight 585 in 1991 and USAir Flight 427 in 1994. According to its findings, an extremely rare malfunction in a hydraulic valve could cause the rudder to move in a direction opposite that commanded by the pilot. The board recommended that all existing and future 737s have a "reliably redundant" system siliconinvestor.com
