UFO Sighting in Kitchener, Ontario on March 3rd 2016 – I saw an heard invisible boomerang shaped craft well biking past one of my neighborhood schools

I was biking past a local school by my house around 11:30 an i heard what i thought at first was plane going over my head but i looked up to see what it was an i couldn't find any thing up in the sky but i could head the sound change directions so i stayed an tried looking for it a bit more after about 5 mins the sounds started to go away but it then came back behind me an this time when i looked up i saw it it was an invisible shaped boomerang craft with sharp sides as soon as i saw it i tried taking a video but my camera is bad an just took a black photo of the sky an the craft flew outa eye sight. it seemed as tho the craft was looking for some thing an i felt i could only head it cause i live in canada an it was so could that night i could almost hear the could air hitting of the sides of this enormis craft. ill link the black video i took to see if u get any thing outa it
