I've had my beady little eye on that Gnat for some time, one of my favourite aeroplanes of all time, a right little sports car!
Fully endorse comments made so far, Newark has slowly but steadily evolved into one of the best aviation museums in the UK. The new hangar will hopefully enable them to consolidate their collection - for example they now possess the only Varsity to be preserved under cover. The Swift looks fantastic too.
The only slightly negative comment I'd make (and I have to say I'm lothe to do so) is that the Shackleton and Hastings could do with some concrete footings and axle stands; the ground appears not to be supporting their weight very well.
Other than that very minor point, hats off to Newark!
