As he got close to the gate, but not quite there yet...he had to push the power up on the L engine to get those last 3 feet and...

Sucked in the yellow AC hose laying on the ramp by the jetway and trashed the engine!

I was sitting reserve in BOS and was called out to DH to LGA, to fly that 757 a couple days later, with the new L engine, back to ATL.
The mechanic in LGA told me it cost about $10 Million for the engine.
