Inside the F-35 Joint Strike Fighter
The BBC has been given exclusive access to film the world's most advanced fighter jet - the F-35 Joint Strike Fighter, built by Lockheed Martin for the US and UK military.
Britain had planned to buy around 150 aircraft for the RAF and Royal Navy - but with each plane costing at least £70m that number is likely to fall.
Squadron Leader Steve Long - the first Royal Air Force pilot to fly the Joint Strike Fighter - explained its unique capabilities to Jonathan Beale.
