353,000 tons travelling at 650 miles per second creates enourmous
air resistance - this will heat the reindeer up in the same fashion as
spacecrafts re-entering the earth's atmosphere. The lead pair of
reindeer will absorb 14.3 QUINTILLION joules of energy. Per second.
Each. In short, they will burst into flame almost instantaneously,
exposing the reindeer behind them, and create deafening sonic booms in
their wake. The entire reindeer team will be vaporized within 4.26
thousandths of a second. Santa, meanwhile, will be subjected to
centrifugal forces 17,500.06 times greater than gravity. A 250-pound
Santa (which seems ludicrously slim) would be pinned to the back of
his sleigh by 4,315,015 pounds of force.
In conclusion - If Santa ever DID deliver presents on Christmas Eve,
he's dead now.
