Imagine our 5 skytyping aircraft flying in a straight-line formation at 10,000 feet altitude. On command, we activate our on-board patented computer/software system and a signal is sent to each aircraft to emit a “puff”. The “puffs” create characters which in turn create your Sky Billboard™ message. Sky Billboards™ resemble dot matrix printing. The average time to skytype a character, “The size of the Empire State Building”, is only four seconds! The hang time for a 5 mile long (20-25 character) Sky Billboard™ is three to seven minutes.
