people ask how far drone works 1 comment says drone operator was in a helicopter - which might make sense somewhat - otherwise, questions not answered - maybe not legal operation of a drone - which I think is only supposed to operate line of sight from the operator san luis obispo county I suppose if you had 2 drones - and used 1 as a comms relay - you could operate a drone for 50 miles or more - same applies if the operator is on top of a 5,000 foot mountain or a forest fire tower / forest fire lookout tower -- You received this message because you are subscribed to the Google Groups "massfire" group.
