Thanks, very interesting recording! And great to listen to the calm Aer Lingus crew.
@rustybugs: Concerning hurrying back: with 2 out of 3 redundant hydraulic systems still working fine, they obviously didn't see any short term risk to flight control. Hence, they decided they had plenty of time to fly the plane, walk through all the checklists and make a thorough landing preparation.
The hydraulics redundancy doesn't apply to ground steering (nor to gear door closing) - so they knew they had to be towed off the runway. Still, there wasn't any flight control issue at all, so no need to hurry.
Unnecessary hasty decisions can turn such a non-issue into a catastrophe. Remember the TransAsia pilots who noticed the single engine failure and, within seconds, pulled the engine cut off - unfortunately shutting down the incorrect and only remaining good engine. Had they decided to just keep climbing slowly on one engine, while running their checklists step by step to identify and shutdown the stalled engine - they'd still be alive today. Acting quickly isn't always the best move.
