I think that could make the difference. According to the report, the fire
dept. measured the temperature at the site. Temps issued for weather reports
are taken in the shade under somewhat controlled conditions. They can differ
substantially from the absolute temperature measured on a hot ramp in the sun.


When the tower is reporting 110 degrees here in Phoenix, it's not unusually
for the plane mounted temperature probe (out in the sun, several feet off the
shimmering asphalt) to report temps in excess of 125 degrees.

I flew out of Willow Run in Detroit one August day and the temperature
on the ramp was 110 when the weather service was reporting 102. That
was just nasty even with the windows open and the big fan running.

It still sounds like there is more to this story than simple overloading
or density altitude. Hopefully, the NTSB will be able to put the pieces
of the puzzle in place.
