Airmen and women from both RAF Scampton and RAF Waddington will march side by side through Lincoln for the first time today, to mark 100 years since the foundation of the bases .
Both have been granted the Freedom of the City of Lincoln, giving them the right to march through the city 'with bayonets fixed, bands playing and colours flying.'
RAF Scampton was granted freedom of the city in 1993, while RAF Waddington has held the honour since 1959.
There may also be a flypast as part of the parade, when 90 airmen and officers are expected to march through the city centre, accompanied by the RAF Waddington Pipe and Voluntary Band. The RAF Ensign will fly above the Guildhall to mark the occasion.
Starting in City Square, the RAF personnel will march to the War Memorial, where they will receive the salute at around 11.35am from the Lord Lieutenant of Lincolnshire and the Mayor of Lincoln.
