re: brakes getting hot.

The transportation safety board of canada at : http://bst-tsb.gc.ca/
has an interesting report on that Canadian Airlines DC10 that aborted
a take off in '95 (or was it '96) at Vancouver and ran off the runway.
(Do a search on Taipei and it should be one of the first documents
displayed).

There was mention that after the plane came to a stop, there was fire
which erupted on the landing gears, probably due to the brakes being
very hot. These fires were quickly extinguished by the fire dept. crews
who arrived on site.

The report also has an interesting discussion on the actual speed at
which an airplane can abort takeoff (V1) and the time it takes to react.

This also explains why such an accident during summer (aka: CP) is best
handled with evacuation (because of risk of fire due to hot brakes),
while in winter (aka: Tower Air 747 at JFK) the risk of fire due to hot
brakes would be lesser.  Is that a proper interpretation ?
