Final preparations for this year's international air show at RAF Waddington have been overshadowed by the announcement that next year's event has been cancelled.
Organisers say it is because of work to upgrade the runway at a cost of £35 million.
The Waddington show draws in thousands of visitors every year and is a major boost for the local economy in Lincolnshire.
Adam Fowler has been at the air force base today:
The annual Waddington air show in Lincolnshire will not take place next year because of work to upgrade the runway.
Organisers revealed the news today ahead of this year's show which starts at the weekend. With more than one hundred thousand people expected to visit the airbase.
Among this year's attractions are the Red Arrows and what could be the last chance to see the Vulcan bomber take off from its spiritual home.
RAF Waddington in Lincoln is getting ready to receive up to a hundred and fifty thousand visitors to this year's International Air Show.
The display is now in its twentieth year and it will mark the sixty-fifth anniversary of NATO as well as the 70th anniversary of D-Day.
The Spanish Air Force helicopter display team will also perform for the first time in the UK. Since 1995 the show has raised three point three million pounds for charity. Paul Sall, Waddington Air Show Director explains:
The RAF says no decision has been taken to cancel next year's Waddington Airshow.
The show draws in thousands of spectators every year, but the runway at the base is to be rebuilt.
Fears have been expressed that the work could threaten the show, but today an RAF Waddington spokesperson said it is too early to speculate and they are focussing on making this years event a success.
Aircraft from RAF Waddington in Lincolnshire could be sent to Nigeria as part of David Cameron's offer of help to find more than 200 missing schoolgirls.
The schoolgirls were abducted by Boko Haram militants.
David Cameron said the kidnapping of the girls from their school was an act of "pure evil" as he updated MPs on the support being offered to the Nigerian authorities.
He told the Commons: "Today I can announce we have offered Nigeria further assistance in terms of surveillance aircraft, a military team to embed with the
Nigerian army in their HQ and a team to work with US experts to analyse information on the girls' location."
He added: "This was an act of pure evil, the world is coming together not just to condemn it but to do everything we can to help the Nigerians find these young girls."
Despite the pouring rain in Lincoln this morning, hundreds of people turned out to see airmen and women from RAF Waddington exercise their freedom of the city.
More than seventy servicemen and women marched through the streets - for their first freedom parade in four years.
Michael Billington was there:
The Mayor of Lincoln braved the rain today to watch staff from RAF Waddington march 55 years to the day since they were first granted freedom of the city.
Cllr. Pat Vaughan told Calendar the people of Lincoln should be proud of their local base:
Lincoln was treated to an RAF parade this morning as the Waddington base celebrated 55 years since being granted the freedom of the city.
A flypast had to be cancelled because of the weather, but it didn't put off hundreds who gathered to watch:
RAF Waddington exercised its right to the freedom of Lincoln this morning - with a parade through the city.
Hundreds of people lined the streets in the pouring rain to see the freedom parade return for the first time in four years, to celebrate it's fifty fifth anniversary.
A planned flypast had to be called off because of the weather but that wasn't enough to dampen the spirits.
Group Captain Rich Barrow, the Station Commander for RAF Waddington told ITV Calendar News that history seems to have repeated itself.
RAF Waddington will exercise its right to the Freedom of Lincoln today, marking the occasion with a parade 55 years to the day since the Station was granted the Freedom of the City by the City Council.
The Freedom of the City, in military terms, is an honour conferred by a city council upon a military unit, which grants the unit the privilege of marching into the city, “with drums beating, colours flying and bayonets fixed.”
The honour is usually bestowed upon local regiments in recognition of their dedicated service, and it is common for military units to periodically exercise their Freedom by arranging a parade through the city.
