An RAF jet carrying the defence secretary had its signals jammed as it flew near the Russian border this week.It is thought Russia was behind the incident on Thursday, which meant that smartphones and laptops were unable to connect to the internet and pilots had to use a different navigation system as the plane’s GPS was disabled for the entire three-hour flight.John Healey was travelling back to the UK from Estonia, where he had been visiting British soldiers, when the electronic attack happened.Passengers, who included photographers and a reporter, were told the Dassault Falcon 900LX aircraft could still operate safely. What is your take on the jamming scenario ?
