Sources told Harger that the door came flying off when Boeing was testing the maximum cabin pressure, whilst the aircraft was positioned in its test rig.
"The accident happened to what’s called the “static test airplane,” one of the two airplanes in any new jet program that are built for ground testing only and will never fly. It was during the final test that must be passed as part of the airplane’s certification by the Federal Aviation Administration (FAA).
On Friday, according to Boeing employees, caution tape was attached to all the entry doors and no one was allowed into the building."
The cabin should have been tested several times before now...this was the final test, not the first. It will be interesting to see what phase of the testing the failure happened, how close to final or ultimate load it got.
Blowing your stuff up on the final cert test in front of the FAA and probably a bunch of international certification regulators....damn.
