I honestly thought this was all wrapped up years ago, but it turns out no.

A joint US-Australian military research team is running a series of 10 trials at the world’s largest land testing range, Woomera in South Australia, and at Norway’s Andoya Rocket Range.
The experimental rocket in the trial on Wednesday reached an altitude of 278 kilometres and a target speed of Mach 7.5, Australia’s defence department said.
Each test builds on previous ones, with the latest used to measure heat on the outside of a vehicle in hypersonic flight, Smart said.
The next test, scheduled for 2017, would involve the scramjet engine separating from the rocket booster and flying on its own, he added.
The first test was conducted in 2009 with the project expected to be completed in 2018.
The last I read of it was this;

2002 This was HyShot’s second attempt at scramjet flight. Their first attempt was lost as the launch rocket lost directional control, and went poof before the tiny scramjet could launch.
That is a long while back, so hence I thought the trials were over.
Nice to know somehow they got the funding to keep it going…. Not sure we will be flying in Scramjet any time soon, but hey, my grandkids might….
Thanks Woomera.
