As a professional pilot since 30 years and former RC hobby pilot, as a youth, I am surprised about part of the nonsense posted here....
For example: "Somebody could clearly see the drone in a distance of 2 miles." I assume NM.
Congratulations to your good vision.
Well, I prostrate myself before you and your superior knowledge. I've only held my ATPL for twenty years (although I had a licence and flew some varied and interesting machinery seven years prior to going commercial). And I presently only skipper a narrow-body jet for a major carrier. And I only flew RC aircraft, as a kid/youth, for about ten years. And it was my First Officer who first spotted the drone as we taxied in.
But I must have imagined: seeing it myself, the queue of traffic (all heavies and mediums) waiting to depart 05L as some pillock flew his drone at approximately 1000' at 2nm on the extended centreline, the further delays to departures as the departure runway was switched to 23R with a 7kt tailwind and the subsequent police helicopter that was dispatched to find the numpty.
I apologise for talking about things that I do not know much about.....
