BEags, my friend. I think they may have overlooked the FACT that the additional wiring was, quite probably, acting as a heat sink, conducting the heat away from potential hot spots that could well have caused a serious and dangerous problem for the aircraft and crew. They should have taken the same test airframe back to Nevada for a further few weeks after the wiring had been stripped out. It would have been the only way to be sure.
By the way, does the LOA still cover the cost of the $10 tables in Ceasar's Palace?
