Remarks: A moment to record on photo !! Observe the fireman underneath the aircraft, water blasting away a pool of fuel which had been dripping overnight from the aircraft, because of which, the fire safety officer was refusing to allow start up. Fortunately the matter was resolved as apparently it was only expansion of fuel in tanks (refuelled day before) due to our extreme heat and direct sun at this time of year. Taxied away too quickly for me - and missed the take off !!
