A restored Vulcan bomber is expected to take to the skies on a test flight from RAF Cottesmore in Rutland despite an earlier false fire alert.
The Cold War bomber is due to fly the 30 miles (48km) to Bruntingthorpe airfield in Leicestershire at 1330 BST.
The aircraft had to make an emergency landing during a test on Monday following the false alarm.
Project Manager Andrew Edmondson said the fault on the aircraft was just one of a few teething problems.
He said: "There's people out there who've restored motor cars and everybody knows that once you've restored it, for the first six months, you get a few teething problems.
"We're getting the same thing and they're just bulbs that are blowing, a micro switch not quite working, so it's not very significant."
The test flight is in preparation for an application to the Civil Aviation Authority for a permit to fly during air shows this summer.
