Someone calling. It is the CAA database that you need.

It has happened that aircraft have landed on the wrong LGW runway 3 times. A Navajo landed on the taxiway, then there were the two jet incidents, Air Malta and DanAir I think were the operators. The DanAir came up against a BIA 1-11 from memory.

There has been at least one occasion at LHR with a Trident.

There are several other cases each year, most recently Sao Paulo with a big jet. A TAP 340 springs to mind.

We have had other British aircraft land on taxiways abroad. The Egyptians used to camoflague the runway and make the taxiway obvious and it has worked, but not to deflect Israeli bomber pilots, merely tourist flights.

Taking off on the taxiway also occurs routinely. Sometimes these are not even parallel to the correct runway. Anchorage has more than its fair share of these and of course there was SQ at TPE with the 744.

Then there are the pilots that think they are on a taxiway when it is the runway.....

Then there are the pilots that think they are allowed onto the runway when it is occupied by another aircraft

Then there are the controllers who do not realise that another aircraft is there

Welcome to Spottie's world. His favourite game is driving around an airport at night with the airport ops manager and the ATC manager on-board and seeing if he can force a runway incursion. Only one mental breakdown achieved with the management so far, but working at it.

Then you have the multiple entry lines to a single holding point. Spottie asks the management what aircraft you can pass here. Management do not know and have no rules. Spottie paces it out and says 2 MD80s are ok, but not 2x 767s. Management write this down. Three months later, phone call, "Ah, Mr Spottie, you were right, 2 767s do not fit, do you want the photos?"
