Red Chillie, 'short of the 21 threshold' is either on the runway (if taking off from 03) or trying to land back on 21 with a significant tail wind, which you wouldn't normally do out of choice.. Implying a turn-back.
Of course I have assumed that they were using 03 - with wind at 040 I can't imagine otherwise.
