TTH,
'When you retire' - surely not already!!!!!!!!!!!
I propose, that you propose, to the committee of the RAF Historical Society that they do a one day seminar on the air force in Northern Ireland. However, by time we get to the mighty Wessex, David Toon had already commanded a squadron of Sycamores there in the late 1950s or so.
Anyway, I commend 'Military Aviation in Northern Ireland' and 'Sycamores over Ulster' to you to start your research.
