Effortless,
being an ex mil aviator myself (RN Lynx), I love to see and help facilitate mil A/C dong displays.
I will hold my hand up to being the chap who was getting on to Shoreham ATC to get the bugger down though as I had a shed load of Gatwick inbounds due at the time...
It's always the way.. never happens when you're quiet. Glad it all went OK though!
