The reference to the unmanned large planes at the bottom:

"Mr McAuslan said there was an urgent need for rules to be tightened before much larger unmanned cargo planes - potentially the size of a Boeing 737 - took to the skies."

sounds intriguing. Are we really close to that happening? I was under the impression the CAA restrictions around unmanned aircraft were still very tight.

As an aside, I found the reference quite funny. In an article about how a random drone endangered a plane, it read more like "we need to urgently tighten the rules before people try and fly 737-sized drones over Heathrow!"
