The training ground is just a cover. Actually, it's a secret underground base being developed so he (or rather his colourfully boiler-suited minions) can build his Massive Destruct-o-Ray Gun away from prying eyes until it is ready, then the "training ground" will roll back from the huge underground hatch which will open allowing the MDoRG to emerge glinting before a terrified world which will now be completely at Power's mercy. Bwahahahahahahah!!!
You could be onto something....it would fit in with my theory for Board activity or lack therof.....
In the 1950's Swindon was sprayed by air with bacteria from Porton Down...this was because the MoD knew of aliens living amongst us, who would be vunerable to this form of germ warfare...unfortunately it was a typical 50's military cock-up. The aliens buried their craft under the CG pitch, during the war years, when the CG was under the disguise of being a PoW camp. The floodlights were built in 1960 to act as a transmitting marker buoy.
The ship needs the combined psychic power of 40,000 human brains to be in its immediate vicinity, to be activated, the aliens came close in the 70's, but have been thwarted on numerous occasions by the efforts of special forces. No coincidence that the last owner was called Black and was a shadowy figure at the CG, who no-one quite knew what his motivation was.
The latest alien plot...see Callum Rice, is to hold concerts at the CG in an effort to aggregate the necessary people.
Rikki Hunt, a prime mover in recent years also had a scheme which entailed setting up a network of muslamic rays over the Town, disguised as a wi-fi system, in order to brainwash people to attend the CG, it only failed due to the incompetence of his sidekick Blue.
The CG hosts the mother ship....there are others dotted around Wiltshire. See Cley Hill, Warminster for example...Waden Hill, Avebury....Merlin's Mount Marlborough.
Am I the only one who thinks it's strange that Power....mysteriously appears from time to time and then disappears again...maybe a wormhole. I mean has anybody ever seen him in "Switzerland"...thought not
