We were in LV till that morning. We had five days of brilliant sunshine, light winds if any and temps from 21 to 25 deg C. Of course winds in desert 80 miles away might be very different.
We have done the "Night" tour of the strip by helicopter and it was very, very professional. Aircraft appeared to be in excellent condition.
Judging by the video just shown on TV here they were lucky anyone survived. Serious blaze from the machine.
