I think the runway at London City is less than 5,000 feet long. It has a 5.5 degree glideslope and requires special certification, as I understand...and London is famous for being very gusty.
It's uncomfortable, but a hard landing dissipates a ton of energy (take that, runway!!!) and helps the aircraft bleed off the extra airspeed it may have carried for the gusts.
I think they someone is getting ready to fly A318s to the US in/out of there.
That would be a sporty landing after a trans-Atlantic flight in the winter.
...any landing you can walk away from...
