Why should I have to tolerate planes circling for hours at a time, over the roof of my house, or 50 feet from it whilst they do training circuits?
They circle over me and around me - often well below 500 feet
None of these is at all likely, in my experience. If you have the real evidence, then present it.
attended as a parish councillor his own planning applications at which he spoke (he and the parish council were punished for this)
Parish councils are consulted during the planning process, but all the parish council can do is recommend - they do not decide. District/borough councils do this.
On Saturday a skydiver narrowly missed landing on the roof of my house and only just managed to land on a field at the bottom of my garden. Traumatic and distressing? I'll let you decide.
Traumatic and distressing, no. Slightly surprising, perhaps. If he landed on a field at the bottom of the garden, then he can't really have got too close to the roof of the house, can he? Parachutes descend quite fast, and can't just level off and then fly too far.
Well I and others in this village have objected to planning applications, as is our democratic right, and complained about dangerous incidents to the Council, the CAA, the BMAA, BPA, and employed very expensive specialist aviation solicitors
It sounds to me as though you thought that an expensive solicitor could make sure it all went your way, and that really you are just very cross that you spent all that money to no avail.
