There are hundreds of vacancies in the UK's air traffic control service amid a national shortage, union bosses have warned.
Prospect, which represents the profession, estimates there could be 250 fewer "validated" air traffic controllers than there were in 2019.
And pockets of airspace in UK skies have had to close for up to 30 minutes at a time this year, according to Newcastle Airport bosses.
The BBC joined the team at Teesside Airport to find out what being a controller involves - and how the shortage might be solved.
