A new team leader comes on board in the Autumn of 2017, and it will be his job to design and develop fresh and ambitious manoeuvres for the 2018 season, which marks the RAF's 100th anniversary.

Two pilots attempt their hair-raising head-to-head manoeuvres for the first time, as the team begin their intense winter training ahead of the RAF's Centenary celebrations. And the engineers who fly back-seat also start their own training.

The new team attempt the most daunting manoeuvre of all - rollbacks. Pilot Toby must master low-level flying upside down, and the entire team undergo their annual sea survival training.

One of the jets crashes on exercise, resulting in the tragic death of the engineer on board. The display pilot also sustains a serious injury in the process, meaning an uphill struggle for their replacement.

Eight top fighter pilots dreaming of joining the Red Arrows are put through an intense week of flying tests and interviews. One of the Arrows is forced to make an emergency landing.

The Red Arrows face their toughest test to prove they are good enough to display to the public. Their summer season begins with one of the highest-profile appearances in their history - a royal flypast over London.
