Celebrities Stephen Fry, Myleene Klass, Wayne Rooney and Joe Hart have marked Armed Forces Day on Twitter.
A Hurricane aircraft was airlifted onto the roof of York Theatre Royal today - and the director of the city's Air Museum hopes it will get people talking about the local history of the air force.
The lift not only marks Armed Forces Day, but also the 70th anniversary of the French Air Force arriving in York.
In June 1944 two French bomber squadrons became operational at RAF Elvington (now the Air Museum). They were unique in Bomber Command, with Elvington being the only base to be operated wholly by another nationality. Some 2300 French personnel were stationed at the base.
Today marks the sixth annual Armed Forces Day.
And in the same year we mark the centenary of World War I, there are plenty of events going on across the region to show support for the forces.
In York, early this morning the Hawker Hurricane aircraft, normally housed at the Yorkshire Air Museum, was lifted onto the roof of the café of the Theatre Royal. This month is also the 70th Anniversary of the French Air Force arriving in York.
On top of all this, York will host Stage 2 of the Tour de France Grand Depart, making this memorial especially significant.
The York Military Wives Choir are preparing to perform at the city's Armed Forces Day celebrations.
They will take to the stage at 1.30pm and again at 3pm in a marquee on Parliament Street.
The choir was only established in January this year but has already performed a number of small concerts, including the Ukulele Festival in York and at the Homecoming Medals Parade of the 2nd Signals Regiment in York.
Armed Forces Day was officially yesterday - but many towns and cities in our region have made a weekend of the celebrations.
Today, there was a service featuring the Royal British Legion flagbearers, a parade down Coney Street, to Parliament Street where a salute took place, and there will be a whole host of entertainment in St Sampson's Square this afternoon.
This features the Band of The Yorkshire Regiment, the Military Wives Choir, a WWI cinema and even paintballing.
Around twenty thousand people lined the streets in Scarborough to join in the celebrations for Armed Forces Day. The sun shone, as the band played and the parade got underway.
The Red Arrows performed a fly past during Armed Forces Day celebrations in Nottingham today.
