That’s a case of a newspaper story over blowing things – surprise suprise!
Componants were in deed crated, but whole airfrmaes no, and the Mod/RN were well aware of the two ready to go examples they had in store anway.
WN411 went the usual post service route of A.S. Gannets, LTS and disposal at Abbotsinch, before scrap by Kitson Vickers. The cockpit obviously made into preservation (ish!).

Certainly can’t claim it as a crated aircraft found again.

I remember this one. The crated Gannet that went to BAR was found in a scrapyard in Godstone in Surrey. Not sure of the exact location but it was on a bus route. I’m pretty certain it was in the late 70s but I’m open to correction on that. There was a photo of it in one of the aviation magazines at the time. Don’t know if this was WN411, as I recall there were some issues with BAR and it all went quiet.
