Some interesting comments and ideas are being aired on this thread, and thanks to all those who have contributed so far.

Responding to the comment in post no11 regarding road deaths, during my research into 231 OCU accidents at RAF Bassingbourn I came across a number of deaths of servicemen (not just from 231) involved in road accidents, from wartime right up until the RAF moved out in 1969. So many in fact that I lost count. A large percentage of them happened to be around the main entrance to the base or along the main Royston road.
My point being that to place a roadside memorial at the spot of each accident would be impractical and nigh on impossible, as in locating the exact spot where the accident took place.

But having said that I am in agreement that those killed in such a way are just as important to remember as those killed in flying duties, in my opinion!
