Dunno if anyone has thought of this, but what if you took something like this:

and attached it to a plane? You'd need to tweak the display "print" speed, but with a little be of practice, come up with some awesome photos.

I'm way off being at a skill level to night fly, so mybe one of the more accomplished pilots could have a go?

Would be awesome to print the flitetest logo across some landmarks!

It might even work with the eyes persistence when traveling at speed?

That effect is called POV persistence of vision. Sure can be done on a plane!
I'll google something up for you.

Edit: Google adafruit, miniPOV, or spokePOV and you'll find info on that kind of stuff.

Yes POV is correct - I wrote some code for Arduino flashing a couple of LED's. It is tricky to get to the correct speed unless you have a meter or something to tell when to blink the LED

There is 1 option...at a given RPM of the motor (attach a RPM sensor) you can write code to blink your LED's
(the sensor can blink LED in a suitable speed to RPM but the LED's has to be lit up a certain amount of time to be readable(a couple milliseconds)
So you might need to divide RPM by a factor of 2 or 3 to get a suitable readability...

If you have LED's mounted on the wing - say 10 LED in a row you have to write letters that are 10 points(pixels) high and they are usually designed like an array

When I did mine I only had 7 but it should be pretty straight forward to convert to 10 digits or more...
