The plane tried to land three times but failed.

The plane failed to gain height and plunged into the sea.

The plane approached again at 09:45 and once more failed to identify itself.

Three more planes flew over and failed to spot them.

A third plane, which beeped the following day, failed to come back to base.

The plane failed the next day as well, and the mission was scrapped.

But there are other reasons why planes can fail to become airborne and run off the runway.

But dammit, both the plane and the engine failed us.

Some reports said the plane apparently tried to abort the landing and take off again, but failed.

After the drop was made the plane failed to return to base.
