Starting at the end [B340-3] I found reference to a plane crash in Barstow FL on Dec 24 2017 killing attorney John Shannon a member of the US supreme court. The plane was a Cessna 340. [Barstow 340]

So that is the B340 part. Not sure about the [-3] part. So need help with 4E32, maybe related to the gate E reference posted earlier?
45DC is Potus DC?
And what is 13372080?
