It's hardly recent, but during my time spent on Nauru - 1973 to 1975, there was a 3 aircraft formation fly past/around the island to celebrate the arrival of their newly acquired Boeing 727, flanked by the "junior partners", a pair of Fokker F100's, C2 RN-1 & C2 RN-2. I have no idea of the legality of the formation flight, but it was a very memorable sight indeed.
And sorry .. I have no photo to post. BUGGER!
