I have only now waded in to this discussion but the public perception is that those flying ex military war birds or wealthy boys toys need to be controlled.
Flying the sort of hardware involved in this accident is way beyond the normal risk assessment of a light aircraft however it almost comes in to that area in terms of pilot and airframe capability.
Joe Bloggs can go out an buy an ex military aircraft and fly it on a PPL with little or no restriction.
Despite the high value of these airframes and their display capabilites there appears in recent accidents to be a lack of control risk and experience.
So where does this leave innocent people on the ground?
I am all for keeping these airframes flying but see little purpose in anything more than a low level safe flypast.
