Pilot ingeniously leaves friendly message in sky

LONDON — This airplane pilot puts your dirty car windshield messages to shame.

Flightradar24 — a service that allows users to track flight patterns all around the world — tweeted a delightful playback that reveals a particularly creative use of flight radar.

The pilot used his private aircraft and approximately 40 minutes of his time to trace a friendly message from the skies, which you can watch below:

So simple, yet elegant.

And certainly more refined than the guy that used the same technology to draw a giant sky penis.
