Jealous ! My niece got her Bachelor's in History but decided she wasn't keen on being a teacher and was surprised no institution just handed her a cardigan with patches on her elbows ... to do history stuff .... and things. She's doing well for herself as a bank officer.
Historian, Physicist, military officer or just some normal doofus doesn't matter that much when it comes to speculation, it's about the reaction to an event, the real phenomenon that matters more and that comes down to mindset and personality. Kevin Knuth had the presence of mind to make some very astute observations when he saw some strange stuff over the skies of Wisconsin and his training played a part in that - but he could've just as easily freaked out or made a mistake or made it all up. I keep coming back to the road flare balloon hoax near here that had military and aviation and law enforcement experts preparing themselves for the next War of the Worlds.
