Here's the article that crossed my path this morning. http://goo.gl/bLDHvZ
As Mark W. correctly points out, the drone registration is that of the owner/operator, not the drone itself. A source I came across this afternoon says each operator has 1.5 drones, so the actual numbers of drones is much higher than the 500,000 figure given in the article. Looking at numbers of registered aircraft (conventional) AOPA's figure is approximately 224,000 as of 2011. Their figure is for "active" aircraft. And that was five years ago. Looking at the year-by-year decline on AOPA's chart I would guess current active aircraft, including helicopters and Experimentals, is getting close to 200,000. ************ On the other side of things, attendance at Oshkosh was 1% higher this year than last year. 563,000 people showed up over seven days, and 10% more vendors this year than last. The increased number of vendors were there to sell drones :-) Mike KSEE ____________________________________________________________ Surprising Way to Lose Pounds, Relieve Gas and Bloating You eat right, exercise, but still can't seem to lose those extra pounds. ... http://thirdpartyoffers.juno.com/TGL3141/57a29ddac0fff1dd8263bst03vuc
