Great video! It appeared to happen a lot faster than I first thought.
Is there some official investigation (preliminary) report out? Me seems this MD-80 taxies quite fast (even if he hadn't any failures). Why not using full reverse?
Preliminary report out on the NTSB site, but is very sparse on the facts. Last year's Pprune thread seems to have been archived, but other details were discussed; Apparently the aircraft landed OK after its hydraulic failure, and on the taxi in they shut down one engine to save fuel. Unfortunately the two weren't compatible, and they lost all hydraulics inc accumulator. P1 thought on his feet and selected full reverse, but due to lack of hydraulics the reverser didn't deploy - however the engines did spool up the MREV, giving plenty of forward thrust. Aircraft ended up completely out of control, and ends up bumping into the Airbus.
Final report should be interesting reading.
