Wow day 4 all ready. Time is going whoosh

Here is my homework.
Why is The Red Baron’s plane red?
There are two reasons. Now a lot of young kids think it represents blood. No but good guess. The really reasons are intimation and identification. In World War I he was the squadron captain and they usually had their planes different from the rest of the squadron.
What is a Datum?
Datum is a SAR term. (Search and rescue) It is the location where the missing or lost person was seen. It also could be the location in the center of the search area. The symbol is sort of like a bow tie but on its side or an hourglass.
What is the Occam's razor?
Wow most people who went to this bog had a different reaction. Well anyway an Occam's razor is a way or method of elimination for unsolved mysteries. Like Amelia air heart. There are a lot of theories of her death. Some say she crashed in the water. Others say she made it to the island but died there. With the Occam’s razor the theory of aliens beaming her airplane with a blue beam was eliminated. Well actually they may have used a blue beam. (Just kidding) I might use this on tests. It will be helpful.
My last Question was who was Ruben H Fleet so important.
He earned his Pilot wings in 1917. A little after that he made his own air Plane Company. This helped bring people to San Diego.
Teacher, please give me comments and facts. I would like to learn cool stuff. ☺
