I was outside on the balcony and noticed 3 red lights in a triangle shape over the downtown area fairly high up, and there was a white flash in the middle of the 3 and it was gone. at the same time this was happening i see the air ambulance taking off from london airport and it came around behind me and landed at the hospital so i started wondering if the red lights were a private plane. it reappeared over the downtown up fairly high but just a single red light, then it flashed white and was gone again, and did this a few times. i started recording and it came back for a few seconds then started moving over the west side of town getting lower and lower as it circled back towards me and over wortley village just above the treetops and just disappeared at wellington and baseline, right near here. i was tracking it with the camera and was expecting a crash because i thought it was a plane, but it just vanished into the trees.
