Folks,
My memory tells me that the Commander of the last Catalina double sunrise service was Captain J.P.R Shields.
He kept the rather oil stained and worse for wear "double sunrise hat" from that trip ( and many previous) and always wore it when, in later years as a QF management pilot, he flew an inaugural or other special service ---- like a Royal Flight.
Those of us who flew with him always thought it was a rather nice touch.
Tootle pip!!
