London City has a single short runway, with buildings around requiring steep climb, quiet engine and a great potential for ground damage in case of failure at takeoff. And I suppose they do not have huge aircraft fixing workshops, either. So, what can LCY do about an aircraft which lands there and on being inspected is thought unsafe to take off? Fix it in place? Break it up and dispose of the wreckage by land? Or sail it out to a better airport?

Do the waterways around LCY have the clearances to let an intact plane atop a barge pass through? I suppose the streets and the railways of East End do not.

You really are being ridiculous with this aren’t you? WHAT?????!!!! IF an aircraft went tech at LCY it would be fixed there…why wouldn’t it be? IF an aircraft had an accident at LCY then the considerations would be exactly the same as any airport with a restricted boundary, it just happens to be that the boundary at LCY is primarily, but not exclusively water. I think you should perhaps leave this topic because it seems a bit nonsensical.
