Resident Stephen Davis shared a great pic of the Presidential Marine squadron's MV-22 Osprey looping over Petworth this morning (much better than the far away shot I managed to grab). Stephen mentioned it was the "first time I've seen those circling the neighborhood that I can recall. Louder than the usual chopper!"
I hadn't seen the Ospreys flying over Petworth before this, but I know that HMX-1 squadron (the Marine Helicopter Squadron One, the Presidential Squadron) was getting the twin rotor Ospreys back in 2013 to complement and eventually replace the Sikorsky helicopters already in use.
Here's an article about the Osprey joining HMX-1:
