Regarding the Word Search, at first I thought the key word was "Columbia". In 2003, the Space Shuttle Columbia was brought down by a chunk of foam which struck the wing at the speed of sound. NASA had become inured to the risks of flying foam chunks. So I was thinking here it meant a small risk, that under the right circumstances could be fatal. What risk, we don't know yet.
Then I noticed, over on the right, "Rapollo". Here is discussion about a 'Wall of Light'.
Rapollo is a perfect name! Apollo is the label of plausible deniability, the disguise they built into the Word Search.
Hell yeah! (5:15-5:40):
Holy fuck, it blows my mind! This is my theme song today.
