Pilot mistook Venus as another plane and send plane diving

A report released on April 16, 2012 by Canada's Transportation Safety Board describes what happened on January 14, 2011.

The first officer on Air Canada flight 878 from Toronto to Zurich, Switzerland, was tired and needed a nap. The "controlled rest" is legal and an accepted procedure in order to improve on-the-job performance and alertness. With the captain's permission, the first officer drifted off for a few Zs.

While the nap is supposed to last no more than 40 minutes, the first officer slept for 75 minutes and woke up feeling unwell, the report states.

By that time, the captain had turned on the seat belt sign for some expected turbulence. There was also a U.S. Air Force C-17 nearing the Air Canada 767.

The first officer saw a bright object ahead of the plane -- the planet Venus -- and mistook it for the approaching C-17. The captain corrected him and said the C-17 was straight ahead and 1,000 feet below.

At that point, the captain of the Air Canada jet and the C-17 pilots flashed their planes' landing lights at each other to acknowledge their position.

But the first officer, still believing that the object in the sky above him was the cargo plane, initiated a dive to avoid the perceived imminent collision -- sending the jetliner toward the Air Force plane.

The captain saw what was happening and immediately pulled back on the control column in a frantic attempt to increase altitude. As quickly as that, the C-17 passed underneath the Air Canada jumbo jet with 103 people on board.

Within seconds, the plane had gone from its assigned altitude of 35,000 feet down to 34,600 feet and back up to 35,400 feet before finally recovering back to its 35,000 feet cruising altitude.

It sent passengers who were not wearing their seat belts flying.
