Earlier this month, one of the Navy’s “doomsday” planes suffered millions of dollars worth of damages due to a bird strike that occurred while trying to land.

The E-6B Mercury, a plane meant to play a vital role during a nuclear war, was performing a maneuver that would include a brief touch down before taking off again at the Patuxent River Naval Air Station when a bird hit one of the plane’s four engines on Oct. 2. There were people aboard the flight when it happened, but there were no injuries and the incident remains under investigation.
