Yeah, that doesn't quite qualify for 'airworthy' - even Spitfires out of annual aren't airworthy. However, there does seem to be good merrit to this news posting - i.e., there really is something there to be dug up. The ground penetration scans which have been made seem more than convincing enough to believe they are of these buried Spitfires. It's been known about for more than a decade now, but there has never been a policatal atmosphere, like there is now, to be able to recover what's there. The stored cache of Spitfires, for which these are believed to be, are former RAF Mk. XIV's and possibly some Mk. VIII's, buried around 1946, with the intentions for possible recovery in the then near future (due to the political climate at the time, involving India).
Based on what I've read from those directly involved in the Spitfire circles, there really is something to this all, which is very exciting - at least the evidence presented thus-far, is very worthy of an expedition to dig up what's there.
From the Telegraph: "A team from the UK is already in place and is expecting to begin the excavation, estimated to cost around £500,000, imminently. It is being funded by the Chichester-based Boultbee Flight Acadamy."
I'm looking forward to sitting back and seeing all that comes of this!
