About those magical flying reindeer of Santa's.....
Santa's imaginary team of magical flying reindeer have countermeasure systems. The rear chaff ejector ports were incorporated with all subsequent replacement units starting just before the Korean war in 1950.
I also found out about Santa's TOP SECRET for getting them to fly their miraculous circumnavigation of the globe in just 24 hours. Every year, starting on the on the morning of the 23rd of December, he feeds them with a liberal amount of special magical flying reindeer food consisting mostly of Chili Con Carne with beans made with Trinidad Scorpion Moruga Chili Peppers.
Ya. Santa ithen had to nstall a full width mud flap directly behind the back pair of critter. He also must wear a size6XXXL Simpson Fireproof red and white flying suit, and full face helmet, too.
