A question on reversers

I read recently the C-5 that crashed at Dover, DE had a #2 engine
reverser unstow right after takeoff. The crew attempted the approach
with full flaps instead of partial flaps per the POH and the sink rate
was too high to overcome.

It was an "unlock" indication which is one step before an "unstow". They
shut down the engine in question to prevent an aysmetric deployment.. I
THINK i saw that they had pulled the opposite side engine (#3) back to
idle for some reason (directional control presumably... but I would have
thought the rudder would have enough authority for that..)..

I heard the full flap thing too.. but my version has them retracting
from full to some partial setting, and that the airplane was flying
below the stall speed for that weight and flap setting, and then simple
physics took over.

The report also said that after securing the #2, they continued to
operate the #2 thrust lever instead of the #3 which was still operating.
Dead foot, Dead engine.
