All the sleighs in us at Santaland are custom built and maintained to our specifications. After all the sleighs are exposed to massive forces and the smallest fault would cause a catastophe. The MIT study stated:
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.
Of course that was based on silly science, our science says otherwise. In spring this year, news came out that the mountain flower sleighs will be replaced with some from the amazon that are currently enjoying a vacation in california. Flyertalkers of course latched on to the most improtant topic of what kind of seats will be in the sleighs. Find the thread for todays clue!
