Gives a new meaning to “flyover country.”

Most flight paths are relatively direct lines, from point A — the origin — to point B — the destination. There are slight deviations, but it's typically straightforward.

But that's not the case with Boeing 4, a flight that from Wednesday night through early Thursday morning was drawing itself in the sky, which you can see on FlightAware.

The Boeing 787-8 took off from Seattle on Wednesday afternoon at 3:38 p.m. PT. Its mission over the next 18 hours: to complete a flight path that bears a striking resemblance to a Dreamliner.

This isn't the first fun flight path, of course, but it is one of the most meta.

As Flightradar24 pointed out, this kind of long flight — which carries no passengers — is typically performed to test the aircraft or one of its many components.

The flight completed the plane shape a little after 9 a.m. ET, and will return to Seattle at approximately 9:24 a.m. PT.
