There is a link to a picture of an upside-down G-BILK here

Dunkeswell is (or was) the highest licensed airfield in the UK. I don't think that 'LK could have reached it. She doesn't glide uphill all that well! Farway Common is not always so easy to find - just ask pilots who attend fly-ins there! It is splendidly kept however.
Perhaps heading towards Exeter Airport (getting closer to the Airport's RFF all the time) was the best option available.
