The KC-46 Pegasus program continues to be a problem for Boeing.  Delivery rates are lower than planned and articles describing the shortcomings in the jets continue to get circulated.  They have a long way to go, and Boeing is going to have to spend a lot more money before they are fully capable.  Meanwhile, jet do continue to be built and delivered.  The earliest jets were given civil registrations because they were undergoing a civil certification program as well as a military one.  Two of those jets are now back at Everett getting reworked – presumably because they will ultimately get delivered to the USAF.  I shot a couple of them on the airfield while up there one sunny weekend.
