Helicopter

Mrs GOG and I were both out in the garden with our cameras, looking for suitable subjects to blip, when all of a sudden at very low level, overflew a number of short-take-off and landing aircraft, together with some helicopters.  They were moving very fast and I had trouble tracking them long enough for the camera to focus on them, this was the most successful picture I took of any of them and it is obviously a helicopter belonging to the United States of America.  I therefore suspect that this was part of a rehearsal related to the Obama visit this weekend; beyond that I can guess nothing. So this is today’s blip.
