The last time I saw a helicopter hovering near my building, I found out it was due to the shooting. So obviously I was surprised to see them hovering over downtown again. I can still see 1 of the helicopter just hovering at a distance and (at least) two fast helicopters doing rounds over downtown. Update:There was a public service annoucement regarding this practice.
It turns out that the armed forces are doing some kind of urban flying training. That is good to hear but I have noticed that people on the streets are looking upwards as I was and look surprised. I hope people driving vehicles are looking straight ahead!
PS: Will get some pics up here soon.
