Airport drone disruption: All major UK airports to have 'military-grade' protection

All major UK airports now have or will soon have military grade anti-drone equipment, the government says. It comes after the military were called in to help when drone sightings caused delays for around an hour at Heathrow on Tuesday. And drone sightings at Gatwick caused major disruption affecting 140,000 passengers before Christmas. Earlier, the defence secretary said it would "not be right" to ask the RAF to respond to similar incidents in future. Gavin Williamson said all commercial airports needed to invest in anti-drone technology.
