Last week, it was back to the future as half of Australia went into lockdown and state borders slammed shut.

On this week's episode, host Phil Tarrant and guest Adam Thorn talk through the sobering events and ask how long airlines can hold their nerve and not stand down workers.

Plus, the pair chat about the effect of Australia reducing its overseas arrival caps. How much harder will it make it for the country to remain open, and for stranded Aussies to get home?

Finally, we celebrate the ingenious targeting abilities of Army's super smart Shadow drones, and a new era of space and aviation collaboration.
