Here in sunny Darwin windows have been rattling and some dogs have been annoyed as the skies are frequently filled with the roar of jet engines as exercise Pitch Black is underway. It's a big Air Force exercise that includes many nations from the region. During the exercise though RAAF Darwin has an Open Day and it's a great opportunity to see modern military equipment on the ground instead of roaring past above our heads. Me and the kid went along and here are some photos of what we saw. I will number them and you can figure out what they show. Nearby is the excellent Aviation Heritage Museum and they had some interesting aircraft on display as well.
