The
WAYBACK MACHINE has archived some of the
Project Get Out & Walk website - for example the
Australian section is at the link mentioned above which has some
RAAF Vampire ejection information:

There are other parts of the 'Project' website however I don't know your particular interest except VAMPIRES. The WAYBACK MACHINE seems to be difficult to navigate while my time to do so is limited along with my own interest which would be SKYHAWKS and I have those pages already.
