If you were at the 2015 Avalon Airshow you could have trailed a real LM F35 helmet as did I. Not particular well moulded to my own pointy head but a LM rep was there holding it in place helping you get a feel of what it's like to use it - magic carpet ride is an understatement.
Re the the G650, well I had the private tour of the G550 and considering they've sold almost 500 of them I can understand why they keep turning up at Avalon.
Avalon Airshow 2017 was yet another great show, and again I would like to thank the participants, helpers and organisers for making it so.
