Does this mean when the Airbus landed, there was a Coast Guard plane on the runway? Seems like the ground control had made a serious mistake.

Coastguard plane landing hit airbus on tarmac.

Edit: seems I was wrong. The airbus was landing.

Unfortunately, you have invented this narrative. There is video of the Airbus landing and striking the other plane.

Definitely better links than Daily Mirror out there, avherald.com unfortunately overwhelmed, but in terms of discussion: - Crazy how well the carbon fiber A350 held up given that it seems to have landed pretty much directly on a Dash 8 (RIP Coast Guard team). Looks like trading long term flammability for initial rigidity lived up to the design intent. - Excellent evacuation job, especially as it looks like on some vi…

I wonder if some kind of "TCAS" for runways can be implemented - once the controller clears an aircraft for a given runway, some antennas start broadcasting that aircraft's identifier so any equipped planes approaching the runway can tell whether they've been cleared for it.

For planes on approach, the existing ILS antennas can be reused but I'm not sure whether that will work on the ground - do the ILS antennas cover enough of the ground to accurately target a plane that's approaching the runway perpendicularly (off a taxiway, etc)?

Two types of systems already exists on the ATC side of things. There are red stop-bar lights at each runway entry point. Pilots are trained never to cross a red stop-bar even if told by ATC. The controller has to press a button to turn the lights off, and they automatically come back on after 1 plane has passed the lights.

In larger airports with an automated system, the system monitors the runway occupancy and approach sector. If the runway is occupied or an aircraft is on final within a certain distance, the system throws an alert before the stop-bars can be turned off.

On top of that there is also an autonomous version of this system that will use red lights to indicate a dangerous runway status (e.g. aircraft on approach) at each entry point. And the other way around, an aircraft line up for takeoff (but holding) will get red lights if any of the entry points further down the runway are crossed.

Nope, that narrative was largely a myth. The people at the back by and large died instantly in the crash, without even time to undo their seatbelts. https://en.wikipedia.org/wiki/Aeroflot_Flight_1492#Evacuatio...

ASDE-X should warn the controller, not sure if it's installed at that airport
