My hearty congratulations to the AB-139 team. This is a great achievement, and they should be rightfully proud.
I do note the uncanny similarity in flight hours to the S-92, 1575 vice 1600. There is a story to tell with that. With a typical structural or certification test hour running about US $30,000 to 40,000, the cost of flight test alone for certification is pushing $50 million!
