Isn't that a little dangerous in the "one engine off" case?

That is what a NASA engineer told me too. I spoke to him during an SAE
conference several years ago. NASA was involved in the analization of both
the YC-14 and YC-15. During takeoff and landing, symetrical lift is
critical. This engine out scenario contributed to McDonnel's "winning" the
competition, although there was no production contract. The design
requirements changed, and the designs were recompeted with an aircraft large
enough to carry an M-1 tank. This led to the C-17. Boeing's entry was a 3
engine variant of the YC-14.

You mean CoANda effect, after Henri Coanda.

And actually, for this particular plane, boeing called it "USB".

any port in a storm, when it comes to aircraft design, eh?
