There won't be a formal investigation into a near collision involving a Porter Flight last week.
The Transportation Safety Board was looking into the incident between the flight from Ottawa to Toronto on Monday, November 14th.
However, they haven't been able to figure out what that unidentified flying object was, so they are essentially dropping the investigation.
Two crew members were hurt, when the pilots took evasive action, about 55kms from the Billy Bishop Airport, at an elevation of abou 83 hundred feet.
Investigators originally suggested the object may have been a drone, but now they say based on the description and the height, it's unlikely.
But they have no idea what that object was.
There were 54 people onboard the flight, and none of the passengers were injured.
