Interesting I have seen a DVD related to their operations just a few weeks ago. It seems they always do intersections take offs and most of the times they tanker fuel from Sharja. Maybe this day they were lucky enough not to tanker or with a low load factor.
From FR24 I saw the coming back flight left on time, I think with the same crew. As for sure immediately after take off this mistake was clear to the crew, to the control and to the management, wouldn’t have been better send a standby crew to do the flight back? I think their mood was terrible.
