Dick,
Why your obsession with Proserpine?
What about the 150+ seat jets that fly into AYQ (YAYE) without radar?
Radar would be lovely but unlikely. It's quite safe because we have a sound system in place. One where directed traffic is given.
The problems occur when you push your VFR no radio/don't talk system, so that we can't be reasonably sure we know where all the traffic is.
Sheesh.
