London's Heathrow Airport Halts Departures Over Drone Sighting (cnbc.com)
London's Heathrow Airport halted departures on Tuesday after a report of a drone sighting, less than a month after a similar event crippled operations at a major U.K. airport. From a report: "We are currently responding to a drone sighting at Heathrow and are working closely with the Met Police to prevent any threat to operational safety," a spokesperson for the airport said. "As a precautionary measure, we have stopped departures while we investigate. We apologise to passengers for any inconvenience this may cause."
Could a few dozen drones, a few at each of major airports, with some nice shiny radar reflectors, clog the air traffic system? They could pop out of parked cars spook everyone, to hide after a minute or two, or be replaced by the next one in the queue. Can it be that easy? I would hope not.
Stage 2 involves deploying drones that somewhat resemble pigeons.
Stage 3 is where the relevant authorities discover they can't tell the drones from the pigeons, and all air traffic is halted, permanently. The pigeons win.
