What do you want to bet, when any 'problems' are fixed, it will become
very successful for Boeing, much like the B747 was, oh so many years ago.
With that aircraft, I was kept busy for a year delivering various bits in a Skyvan to Seattle...and the 747 swept all others aside.
Airboos, phooey...they can't even get the FD to give correct pitch indications for takeoff, at least on the EK machines...
