Blackhawkes over CBD

[Mark Grima]

Hey guys,

Just went for a stroll outside and heard a strange noise, walked to get a view of the harbour and CBD and saw 3 (what I think were) Blackhawkes doing laps from the Eastern Subs (SCG/SFS way) over towards the CBD, flying directly over the Navi base at Woolloomoolloo turn right and fly at a very low (approx 200 - 300 feet) altitude north past Bradleys Head where I lost them. However judging by the time it took them to come back into view they were probably only goin up to Middle Head before coming back.

They did this for about 15 - 20 minutes before the three of them shortened their track and just did little laps between Bradleys Head and Middle Head(ish). I watched them for about another 5 minutes before it started to rain and I scammpered up the hill to the safety of my office.

Any ideas what they were doing?

Cheers

M
