Anyone see the unusual aircraft over Norman late this afternoon / early evening? Had the look of a tilt rotor bird like an Osprey. AW was working on a civilian version of a tilt rotor, but didn't expect it until 2016. Curious if anyone saw it that could identify it.

That would explain why my windows rattled like they did.
I didn't see it but I knew something flew over the house fairly low and was a lot louder than a normal helicopter.

dinna see it.
dinna hear it.
dinna feel it.
probably came through in between looking for a number to make a call and huzza? wut? whoa, how long have I been napping.

I heard / felt it shake the windows too, but didn't go over to my window to see what it was. Would have been interesting to see.
