Thank you to all of you for your kind words, it's brought a big smile to all the family recalling these stories.
I believe his habit of whistling whilst coming up the Heathrow Tower steep stairs at the end of the night shift gave the ATC staff up there enough time to clear away the old cups and newspapers before he puffed his way to the top. Such thoughtfulness!
I'm currently working my way through his ATC paperwork, fascinating! For example he was awarded £3 by the MoA Central Suggestion Scheme Committee in Sept 1965 for suggesting that the reporting point of Abm Dieppe should be renamed Fecamp to avoid confusion to both London and Paris ATCCs. Shortened to FC and then realigned to ETT Etretat (ETRAT) on the new Amber 34. He also introduced 'VR' (Veule-les-Rose) on Amber 1, VRO then VEULE. His legacy lives on!!
