After an F35, flying from HMS Queen Elizabeth, crashed into the Mediterranean the pilot ejected and was safely recovered to the Aircraft carrier.

In this week’s Sitrep we look at the two most urgent tasks now, to find out why the crash happened, and to recover the plane which is packed with top-secret technology that the UK does not want enemies to get a glimpse of.

Blowing up a satellite, massing troops near Ukraine, and getting involved in a migrant crisis. We ask what is Russia up to?

A world leading expert tells us why he’s changed his mind on the risk of a biological terror attack.

And we have the story of a world-record flight using a fuel made from nothing but air and water. We ask the manufacturer of the UK’s fighter jet engines if the fuel really could power a carbon-neutral Royal Air Force.
