They did very well under the circumstances
. Landed a bit fast, perhaps, but was of no consequence. Perhaps that was because of reduced elevator authority.
Well done for using the M word too; given the possible interference to the elevators, that was a good call. He also knew where he was...his initial call included where his intended landing place would be.
This is an incident reportable to AAIB, as I'm sure will happen.
Baggage doors aren't hinged at the back, so I would be interested to know the engineering diagnosis of the failure. Hinge failure elsewhere? Or latch failure?
In the UK we are quite well trained to use Mayday and Pan calls; my American cousins just don't seem to have that mind set.
Again, well done to those onboard for being very sensible and flying the aircraft!
