January 9 2013 – Mississauga, Canada. These strange sounds were recorded @ 2:15pm from the Sky of Ontario. The loud strange noise lasted around 5 minutes and is similar to that of an airplane passing by. The recorder explains he tried to figure out the exact source of the weird sound, went out front of the building visible in the video then to the back without any luck. No planes were flying by at this time. Moreover he did not locate any heavy equipment around. Finally the sound did not come from the wind (you can hear the wind actually when he is walking back and forth to try to locate the source). So what could it be? A military jet? The noise lasted 5 min or more which is too long for any military jets. Maybe is the sound coming from another locality (sound travels far due to cold weather)? Well let me know if you have other ideas!
