IMHO- having been on the initial 767 production in the early 80's- andalso worked on b1 and b2 programs - somewhat aware of the first 767 tankers fiasco and how it happened -and still knowing many current BA employees- the simplest explanation for FUBAR issues relates to miss- management, MDC- st louis types- Jack welch wannabees, and a focus on faster better cheaper mantra.
Note that the military versions of the 737 series, incuding very successful Navy p-8 program was run primarily by old commercial types with minimum interference by the ex MDC fighter jock types. Not so for the 2001-2003 767 tanker fiasco, the 787 cluster**, the dash 800 737 wing design types( ex MDC ) who stalled for a few years the Aviation partners winglet improvements now standard on most aircraft.
