I guess it was quite a pilot's aircraft.
I remember arriving in Muscat as SLF and we did a visual approach from the west to runway 26. We rolled wings level over the end of the runway and touched down a few seconds later.
Performance of the 100 srs was a bit limited in high temps. Normally the BA flights came through MCT around 0100 to 0300 local. If delayed and departing after around 1000 local, a tech stop would be required to get to London. One was sitting on the end of the runway burning off fuel for about 20 mins. as the temp rose to get down to RTOW. A lot of sand blowing around.
