Mysterious Greenland Shark

Witness statement: Somewhere near Greenland. Flying to Canada. Felt like UFO. Flying opposite direction of the plane. Not straight but more like going down in high speed. Mohit Mahajan What is the black smoke like trail and is it the Sun in front of a unknown origin craft? Lot's about this sighting doesn't make sense. Thoughts on this are welcome 👍🏻 Send your UFO reports to me through Instagram DMs where you can send videos and photos. @ufosightingsfootage is my handle 🙏🏻 Google: ufosfootage
