From the Attack Helicopter Display Team Facebook page:
'It's with regret that we have to announce the fact that we won't be displaying the Apache in the 2018 season.
The commitments of the Attack Helicopter Force are too great to be able to support standing up a team for this year.
Be rest assured that the decision wasn't taken lightly and was considered at the highest level. We will retain our capability to display and aim to be back for the 2019 season. In the meantime, we wish all our fellow teams the best of luck for their seasons and thank you, as always, for your huge and continued support. AHDT'
In 2017, the 'Attack Helicopter Display Team' displayed the AAC Apache attack helicopter and put on a superb display along with pyrotechnics. At the end of the display it hovered at crowd-centre before there was an explosion and a huge impressive wall of fire behind the Apache.
