I lived near Bovingdon , near not close and still in Herts and have vague memories of military pistons heading to or from the airfield. QQ has a great list that would have been fantastic to see for variety.
I was intrigued to see the last one on the list which was presumably there to fight for lower taxes and immigration control as being RepublicAN Thunderbolt=probably predictive text . Maybe Trump will try and steal the phrase I am am sure he would like to be seen as a Republican Thunderbolt
