I didn't know that a Chinook had that range!!
601: The caption text was fairly scrambled but I worked out this must have been A3-36 taken from Darwin to Tindal (Northern Territory) as a slung load. Around 280 km or 150 NM, see:

But at least the Mirage had a safer ride than the AW119. That said, it had previously also been a 'dart' as the linked description reveals.
Update: Oh, I was slow to get your joke! :-)
