I still don't really understand. Unless the 737 was about to crash land right on top of the 330, it must have turned right well before the airport. If the 330 took off, it would have been a few kilometers beyond the airport before it turned right itself. I just can't visualize this 800m thing. If the 737 was so close it's go round intersected a plane that took off, this story really should read "737 narrowly averts crash landing into an airbus that was mistakenly let onto runway". Smells like a coverup to me.

There are standard "missed approach" routes published for each runway. Generally they involve flying more or less directly over the runway before turning to circle around for another attempt. The 737 flew that route. As they were doing that, the 330 was taking off and turning in the same direction after takeoff (as they were directed), so they both wound up near each other a few km beyond the runway as they were both turning to the right.

  Now I am just flabbergasted. How on earth could they let the 330 take off in that case? And it still seems to me if the 737 didn't execute a missed approach, there would have been a crash on the runway. That is just as big a deal as the 800m flyby. This story should be a bigger deal than is being made out.

    You don't get the throughput major airports require without vectoring planes to land before other planes have taken off from the same runway. If the plane taking off takes too long you tell the landing plane to go around. This happens daily - I've had planes I'm a passenger on do it twice. It wouldn't have been a big deal at all except for them both having been directed to turn right in conflicting ways.

    This is entirely standard procedure. In Europe (and ICAO standards) the controller will say to the second plane "number 1, traffic departing ahead" to let them know and then only say "cleared to land" after the other plane has left the runway. In the US this is a bit different, they will say "cleared to land, traffic departing ahead" and are trained to cancel the landing clearance if the other plane isn't off the runway fast enough. In both cases the second plane is made aware of the first, so they're ready (should always be) for a missed approach.

When you're approaching an intersection controlled by a traffic light, do you feel the same anxiety? There are cars occupying the same bit of road that you're going to be occupying in a few moments, and if you don't stop at the light, there will be a crash. I'm guessing you don't give it a second thought (you may double check that traffic has stopped before proceeding, and pilots do the same thing when they're landing).
