From reading a many many posts on the KC46 subject and others, and having spent more time at ' the lazy B ' than most posters, ( now retired ), and followIng other boeing - 737 - MAX NG threads for several months, I have to agree with tdracer and fdr and a few others- they do know what they post. As a newbie here I cannot of course post links.
But I can state the real story not shown here re history of KC46 ( KCX-767 ) starts way back in 1999-2000 and pushed as a lease in aftermath of 2001 as 767 line was running down at the time. And of course the mcDonnell douglas jack welch crowd involvement, a few club fed types, etc.
And it all has bearing on the current mess
