I fly in and out of LCY daily, as a left hand driver.
Some of my landings have been harder than others. This is no different from when my f.o or my self have made positive touchdowns in ZRH or EDI for example.
You have enough time to judge where the t/d is going to be, so a g/a is possible with enough time. Of course, if needs be, touch down, power up and g/a. A g/a dosn't have to occur in the air.
I have made a few with a late touchdown, kept the speed up and went around at 0ft!
Every approach and landing is and should be challenging. If you are landing an aircraft with 100pax on board and not even thinking, "I need to concentrate on this and get it right" then I would be worried.
Airports like LCY keep the crews in top form.
..............................
Fridays accident was handled very well by all the airport staff.
The Airport Fire crews were there within minutes, as with the airport busses and so on. Staff were pulling passengers away from the plane in a very well organised way. An aircraft at a holding point near the runway had it's engines shut down very quickly.
I don't think we should forget, how close this could have become to being a "major" or "fatal" incident.
