Inmates could escape jail on drones, warns top prison governor
Drones to replace the helicopters and rope ladders used for decades in tens of thousands of prison escapes. And before them there was that guy who escaped in a hot air balloon (though superman caught him pretty quickly). 
Not sure why they need to spend £20k on a drone to escape anyway… if they just wait for a few weeks the prison service will probably just let them out by mistake anyway,
