Avenger FN821 revisit

Took a trip out with a friend Jarratt Mycoy to the crash site of F.A.A. Avenger FN821 which crashed on Trum-Y-Fawnog ,Llangynog  during a unit move flight from Gosport to HMS Robin in the Orkneys, north Scotland via Machrihanish on the 3 February 1944 with the loss of all on board,  the plane ran  into very poor weather over the mountains which led to a loss of control , during it's final dive the aircraft lost a wing.

On my last visit the trees were still up and the site well hidden but looked pretty much as it does today though I note the escape handle that was present looks to have gone hmmmm
On board were=
1st Pilot S/L William Seddon Appleby
2nd Pilot S/L Ernest Hartley Green
Observer S/L Joe Lupton
Some sources also list a 'Passenger' but as yet I have no info on this
