That brings up another issue. What would you estimate the flight
characteristics of a B-747 to be if the other engine on the wing with
the dead engine had failed? I would guess it would be virtually
uncontrollable without reducing power significantly resulting in a
forced descent.

Nope! It has a two-engine VMC around 230 KTS. Its two-engine
service ceiling would probably be less than 20,000' depending
upon weight.
