Just yesterday (Friday 10.21) we had a chemical spill at the MGP ingredients plant in Atchison Kansas. The best News coverage images were from an individuals Drone. (2.41 min video) here: http://www.kctv5.com/clip/12842922/drone-video-shows-plume-from-chemical-spill-in-atchison In the Newscast I obsered yesterday, the Drone Pilot discussed how at one point he lost his drone in the plume cloud! It appears that he was at considerable altitude at times. I'm in no way complaining in any manner but, it seems I recall some FAA restrictions in licencing once operating above a certain altitude. I think it was 400 feet. I have now today noticed that his video has been removed from some reports. Has there been some firm licensing requirements or, altitude restrictions?
