Last time this happened to me (Dublin) we were over the threshold when the
pilot aborted. Apparently an Aeroflot plane had, quote: 'Got lost' and
hadn't cleared the runway when expected to. We went up in a straight line
and much steeper than a normal take-off. I've also seen go-rounds at
Heathrow happen much closer than two miles from threshold.

Strictly speaking, the decision to abort ought to be made before the pilot
goes to "full flaps", because that inhibits his ability to get away again
safely. When he does that, he's almost committed to landing. Trying to climb
away on full flap is not nice. You cannot safely raise them until you have
enough speed and altitude.

But if it is a choice between a not nice climb out on full flap or mating
with a Tupulov half way down the runway, I know which I prefer.

If there is a Tupolev halfway down the runway, you should never have got
that far. I've done a full-flap overshoot in an Oxford, and didn't enjoy it
much. It took forever to get to a height where I could reduce the flap
setting, even with the wheels up.

I can imagine! Not a problem for a modern airplane.

A landing aeroplane at Heathrow has only got to be dalayed on the runway for
a very short time to cause the next aircraft to go-around. That go around
will nearly always be when the aircraft is over the threshold.

I once saw a lufthansa B737 go-around at Heathrow in the storm of 86.
Controller said a baggage container was reported to be blowing across 27L.
The 737 went around - the wind was so strong that he climbed a couple of
thousand feet before making a left turn - he was still over the threshold!

Same day a Swissair pilot reported his groundspeed as 56 knots on the
approach!

Being sat somewhere down the back of a Ryanair 737 I didn't actually see the
aircraft (it was dark a t the time), just repeating the edited version of
what the pilot said once we regained altitude! We were extremely low, can't
have been more than 30 feet off the runway.

In reality, the decision to go around is extremely late - almost at the
point of touchdown. All aircraft are able to go around safely as they are
very light on fuel anyway. Go around in a modern jet is no more difficult
than pressing the go-around button. The plane will automatically apply the
correct power, raise the nose to maintain a safe climbout speed, leaving the
pilot to raise flaps at the correct speed.
