RAAF Herc's ?

[Mark M]

Have a question that every time I drive base the RAAF base at Richmond that I think I must ask then forget by the time I get home.

Its basically about the C130's that line the apron, where do they fly to im thinking probably Darwin, Townsville and East Timor. Occasionally see one flying into Williamtown when im working up at Newcastle but this is very rare.
And it seems there is nearly always one doing Touch N Go's.

Do they pretty much all use the 'Mentor' callsign now or does it vary and what is the go with ATC do they come up on the civialian ATC am not likely to hear them on my scanner down here in the Shire.

And I can understand for those well in the know if you can't tell me for security reasons etc, but thought Id ask anyway.

Thanks
Mark
