A Trident II is the least interesting thing it could be.

And the US lighting off one of those is pretty interesting. You think this is like North Korea launching artillary in the general direction of South Korea? Maybe we're working on a new way to chuck things into space? Almost seems like it's entering/re-entering the atmosphere.

I posted this to /v/underreported and no one over there gave a shit either.

It was a Trident II test launch by the navy.
