**Matthew:


It would be quite simple in today's aviation. We use the sky writing 
concept, except the air craft could fly in a straight line and we use 
smoke oil, injected into the exhaust. just down stream of the exhaust 
valves. The exhaust flame burns the smoke oil and it exhaust as white smoke.


The oil valve is very fast operating and a series of dots is very easy 
to write.


During the Sun n Fun air shows, we buy it by the truck load in 55 gallon 
barrels.


However, now days, the issue would be, to find observers on the ground 
that can read Morse code,  and to keep it secret, we would need to go 
back to the Cryptographers.


That's a long way from a Quadracopter, and a wireless camera.
