tdracer, sorry to hear that.
The Boeing 767 has been in service for years, the military side of the company has long experience in the AAR role, so there should have been plenty of synergy when it came to converting the 767 for the tanker role....
There were some aerodynamic issues with the Italian KC-767I, but the fixes should have meant that the KC-46A wouldn't be affected in the same way. Also the Japanese KC-767J had an AAR boom, so quite why it has taken so long NOT to fly a KC-46A is perplexing in the extreme.
Worrying to learn that 'management' couldn't even identify a wiring problem...
and ultimately expensive for Boeing. Particularly if, as a consequence, having delayed a large portion of the test programme until
after the Milestone C low-rate production decision, significant modifications prove necessary.
