Re: It's time...
Not the OP but he may be right:
"The number of drone incidents involving Heathrow planes nearly quadrupled from seven in 2015 to 26 last year (Note: The article date means this refers to 2016!), according to reports by the UK Airprox Board."
That's one every two weeks at Heathrow alone just 2 years ago, after previously quadrupling. Nothing to suggest that the trend can't have extended to one every week at Heathrow alone.
