Most loss of coms in my experience are America based Airlines coming off the Nat tracks early morning. & orange ones in the BDX fir.
I assume these are usually resolved without an intercept? The recent intercepts that come to mind are AB2266 from MUC to AGP, intercepted near Toulouse by the French about 2 months ago, BA108 discussed in this thread and today's AF1558 from CDG to NCL, intercepted by RAF Typhoons.
Quick look elsewhere also shows an Egypt Air flight intercepted by Israeli F15s last month and a Monarch flight intercepted by Croatian MiG21s last year.
