An airline crashed above Toronto International Airport, making it the third major airline crash in the last 3 months.

Delta Airlines flight 4819 departed from Minneapolis and was headed to Toronto. During its landing process, the passenger plane flipped upside down and caught on fire, injuring 21 people. No one was in critical condition, and all passengers were safely evacuated from the upside-down jet. 

Authorities are still investigating the cause of the incident. A video from the plane showed part of the landing gear collapse and cut off the right wing, which holds fuel for the jet. This caused it to catch on fire.
