I'll check on the Herc rego later today..
In the B200 pic, behind in the background is P2-EUV, been there for 4 years now with one engine removed, believed in a box a Hawkers. new Avionics refit has been partially removed. I think the aircraft was operated by Pacific Jets, based in POM.
The latest attempts for a replacement is P2-MRM, also a Citation II now parked at Maroochydore since Sept 2017 and due for 'heavy' maintenance. Not flown for 15 months.
