Alex,
I am so sorry to read of the loss of your father.
He kindly supported my research when I was putting together my books on the DH Vampire and RAF aerobatic teams. His generous, enthusiastic and articulate responses to my numerous questions regarding No.71 (Vampire) Squadron and the 1961 CFS Jet Provost display team, 'The Red Pelicans', provided a great deal of integrity to the respective chapters.
I am grateful to him for his unfailing support and offer you and your family my sincere condolences
'Blue Skies'
David Watkins
