Extra money to increase flights at RAF Lakenheath
Normal service has resumed at a Suffolk airbase which reduced flights in April due to cuts in American defence spending.
RAF Lakenheath, in Suffolk, had grounded some of its 75 F-15 jets but returned to its "standard flying schedule" on Monday.
The US government has given $423m (£280m) to temporarily restore flying hours at bases around the world.
It means flights at RAF Lakenheath can return to normal until October.
The jets usually fly for a total of 20,000 hours a year.
Being able to fly longer will help with "crucial training" and development for aircrew and support personnel.
Col Mark Ciero, 48th Fighter Wing vice commander said: "While we are pleased to be able to resume our regular flying hour programme, we should remember that this is not a permanent solution.
"We need to ensure that our aircrew and support personnel receive the best training possible via whatever means we have available, both now and in the future."
