More than half way into testing, the USAF has discovered severe flaws on the tanker, known as “category 1 deficiencies”. Among the most glaring, the tip of its boom has on occasion struck receiver aircraft outside their refuelling slipways.

It is unknown at this point whether Boeing will be able to meet the USAF’s "required assets available" milestone scheduled for October 2018, Everhart adds. (end of excerpt)
