BIRD OF PREY

As I've mentioned before, the sound of these Osprey aircraft is both distinctive and loud - I heard this one coming seconds before I saw it.
This aircraft was probably involved in military exercises going on all week with other aircraft from the carrier USS Theodore Roosevelt (known to it's crewmembers as "The Big Stick"), stationed off the Florida coast for the event.

Footnote: For bad guys, the sight of one of these birds of prey means that you're shortly going to meet a Marine Expeditionary Force...
