Harrowing air traffic control audio reviewed by CBC News reveals the tense moments before a small plane crash-landed near a Toronto high school Monday night.

The recording shows interactions began as normal, with someone on the plane requesting permission to land at Billy Bishop airport.

But just moments later, that person makes an urgent call to the air traffic control operator.

"City centre, I think I might have an engine failure," they said in a recording that was uploaded to LiveATC.net, a website that shares air traffic control audio.

When asked if the plane can make it to the airport, the person on the plane responds: "Negative."

A short time later, they can be heard on the radio telling the air traffic control operator there is nowhere to land.
