One guesstimation regarding how quickly a runway can be cleared for a
landing in the opposite direction. It's not uncommon to have three
airplanes on the departure runway - one accelerating, one taxiing into
position at the end and another (the next for take-off) taxiing into
position at an intersection. Allow 1 minute for the take-off run and
another for initial climbout. As for the other two airplanes, behind them
is typically the departure queue blocking the quickest exit, so they will
need to taxi on the runway to the next free exit before vacating the
runway. That probably takes the same 2 minutes. So 2 minutes minimum. Then
consider the wake turbulence, if it was a heavy taking off - do you really
want to land into the wake? That might cause an emergency all by itself.
Just my $0.02.


So there'd be no hurry then.
