Flight MQ647

The plane was in the air for two hours before the trouble started.

The pilots radioed in that one of the engines was a little sluggish, but they were confident they'd be fine.

A few moments later, they reported that it had died, but they felt they would be fine.

Then there was radio silence for several hours, long past the point they should have checked in.

The final message came just as the controllers were starting to activate the various first responses to missing planes.

Oddly enough, anyone who listens to the message feels we shouldn't look for it.
