Australian Aviation understands that passengers on a QantasLink flight from Kingscote – an unscreened airport – were able to enter Adelaide Airport without proper screening at around 11am.

The halt follows a story published in The Australian over the weekend claiming that Rex had called in a “turnaround team” from big four accounting firm Deloitte and that the airline has been having trouble turning a profit in its domestic jet operations.

The launch provider added that it had earmarked “a few potential sites” and would leverage its existing orbital launch technology but provided few other details.

The accident, which took place during Exercise Talisman Sabre, resulted in the deaths of Captain Danniel Lyon, Lieutenant Maxwell Nugent, Warrant Officer Class Two Joseph Laycock, and Corporal Alexander Naggs.
