|Only one careful owner and the MOD.|
1. A Fast jet (once) flown by the RAF for ground attack and Recce missions. Considering it was designed by garlic eating Johnny Frog it was quite a nifty bit of kit. Although sub-sonic (Wrong... Mach 1.6 or 1056mph) you could just about land the thing on a dirt farm track.
Of course it had to go.
2. Petrol engine originally fitted in the CVR(T) family of armoured combat vehicles giving them a top speed of 'WEEEEEEEEEEEEEEEEEEEEEEEEEEE!'.
3. Large cat sometimes (briefly) seen hanging around Bodmin moor.
