even if they are all glitches or otherwise explainable phenomena, if there is no formal process to record them, there is no way to formally analyze and explain them. those things that seemingly defy the laws of physics could become explainable if we could get more data about them and study them. it's the only way to get to the bottom of this. also further study will help reduce future reports as we then can train people to better understand them.

maybe that object flying mach 3 is an optical illusion caused by some combination of factors. like a mirage. by studying the effects and correlating the factors we'll come to understand them better and may even be able to predict and intentionally create them.

in short, this is by no means a hunt for aliens, but on the contrary, it's a hunt for data to help us understand our world better.
