Hey Mr 'mc',....
Back 'in the day', we used to fly BK to SY, land, park in the then 'light aircraft parking area', just outside said tower building, stroll into the then TAA terminal thru the 4 ft wire gate, have a cup of coffee, then 'stroll' back out to the nice sleek PA24-250, a 'hot' machine of the times,......again thru the 4 ft wire gate, and, you are quite correct - NOT an ASIC or a 'security' guard in sight!!
ALL for No Charge....Gummit aerodrome...
And all just to 'impress' the girlfriends..... Finish it orf with a 'City and Beaches'
then back to BK for dinner at the RACNSW Clubhouse Dining room...VERY nice!
Dems were de days....
Cheers
