Well, it looks like the KC-46A first flight date has slipped yet further. Having missed its April 2015 first flight date, that's now stated to be happening 'later this summer'.....
EMD-1, a 767-2C, has finally flown again but without any boom or pods. It's supposed to fly with those 'in the coming weeks' to certify the -2C's airworthiness before the KC-46A can fly.
Which gives ol' bubba Boeing less than 2 years to progress from first flight to the contracted delivery date for 18 operational aircraft.
