Way back, when I was working at a regional airport in northern Germany, I once had seven light typs lined up on one runway. All were VFR and took part in a scenic flight activity. All crews were prebriefed about the routing and all the pilots knew each other well. We had alltogether 25 aircraft doing these flights which lasted about 10 minutes each. Inbetween we had to work in the normal traffic. It went on all day and it was fun.
