The only surviving German Second World War Dornier Do 17 bomber was to be raised from its watery grave in the English Channel tonight but the rescue was delayed by high winds, the RAF Museum said.
The aircraft was shot down more than 70 years ago during the Battle of Britain and the project is believed to be the biggest recovery of its kind in British waters.
A spokesman for the RAF Museum said a diver will attach a final cable by 9.30pm and then the aircraft will be lifted out of the water.
The operation has been hit by bad weather in recent weeks, forcing the museum to rethink its method.
The new plan involves attaching lifting equipment to what are believed to be the strongest parts of the aircraft's frame and raising it whole.
It will be placed on a barge in Shropshire.
