On the 4th and 5th April there's a living history event on at RAFM Hendon on 4th/5th April, entitled 'Happy birthday, RAF!' due to the proximity of the 91st Anniversary of the RAF's formation. Displays will be dioramas using aircraft in the museum's historic hangars and bomber command hall, from WW1 to inter-war, WW2 and post-war.
I'll be there on the only WW1 diorama with the 22 Squadron Bristol F2b Fighter. The Old Contemptibles and the Great War Society are teaming up for this event to provide a top notch Royal Flying Corps display, using, as well as the superb 'Biff', other original items including a message streamer, Lewis gun drum mag(s), and disintegrating .303 link for the forward firing Vickers
This is the official blurb from the website
"The Royal Air Force was formed on 1st April 1918. To celebrate the 91st anniversary of its foundation, we will have a series of re-enactors on-site in our main halls who will be at hand to talk about the contribution that the people they represent made to the development of the R.A.F and the defence of the U.K. Groups will include members of the Royal Flying Corps, 1930s airmen, World War II Fighter Aces, plus test pilots from the 60s and 70s. "
The superb Grahame White-Hangar, containing a top notch collection of original and reproduction First World War Aircraft will be open all day, 1000-1800 as opposed to the normal opening time of 1000-1200 due to the work going on in the Battle of Britain Hall
