If this was intentional, then this has to be a terrorist attack
It's a mass murder. He commited suicide, and took everyone else with him because he was scared to die alone. This wasn't in the name of a religion or a cause. Not a terrorist attack.
On the day this happened, Tuesday; I took three flights (Chicago to Charlotte, Charlotte to New York and New York to London) and I was ****ing terrified on each one of them.
Also flying over the Alps next Thursday to Milan. Got me terrified too.
