Cannot agree more re possible cause.
A few bits of info regarding the Spitfire replica from a VERY reliable source.
The owner only had it 2 or 3 weeks, but was expierienced.
There is no true dual control trainer, as there is a weight C of G problem with pax in back seat, above a certain weight.
The aircraft has a nasty envelope corner regarding stall/ spin, which needs to be respected, as with Gympie accident in same type....think it was a base to final stall/spin.
And since this is a rumour network, there is a rumor, not confirmed, that the airframe type cannot be insured, but obviously there would be a pax/ground liability available.
Shame it happened, as the replica looked good , but nobody was seriosly hurt , the pilot was home that night, and the " men in orange jackets" did a great job after the incident.
Looked like PB leading the charge.
