+1 We do the same in the Uk. With jets we usually have no more than 4 sometimes 5 in the air at one time. The pilots all stand in the same box and the spotters are behind them. The flight director stands in the box also making sure everyone follows the flight rules. Planes going out to takeoff, taxi out from one end of the box and those landing come in the other side. I have thought for some time that in the USA pilots go far too long way down the runway for takeoff. With the usually overpowered models takeoff runs are normally pretty short. This must clog up things. I personally see nothing wrong with a go around to check the wheels are down but the pilot should tell the other pilots he will be landing the next circuit. This can easily be done when all are standing side by side. The other thing that we see as a difference is the flying styles between the USA and UK is that most of the pilots in the UK do not fly flat out all the time. If you are flying flat out in a low pass it should be shouted out before the pass to the other pilots. The direction of flight is normally dictated by the wind direction and mid airs are unusual when all follow the same direction of circuits.

As with motor cars accidents can happen but when rammed from behind there can be only one person to blame.
