Twitter users in the area have taken notice in the last 24 hours. @doogsta of Melbourne posted this TwitPic of the Black Hawks in action:
Here's a selection of Melbourne tweets about the helicopters:
@martinwarren (Melbourne, Australia): Blackhawks flying over melbourne cbd and inner city again tonight are we being invaded
@downesy (Melbourne, Australia): Blackhawks are shaking my building (circa 1915) more than the freaking #earthquake. Are they doing aerial burnouts up there?
@miss_moo (Melbourne, Australia): hating the Blackhawks doing night maneuvers in the CBD and nearly flying into my apartment - shoo shoo go away...
@adam_hills (Melbourne, Australia): understand that blackhawks have to train but c'mon ppl! every 30 secs past the window!!
@indefensible (Melbourne, Australia): Exactly how long can BlackHawks fly without refueling? And by fly, I mean circle my [expletive] house.
@joel_birch (Melbourne, Australia): @catherineLd thanks. The blackhawks are really quite alarming. Can't hear myself read and my hair is currently swaying above my head.
