Yeah, Sure.

 He was a good NCO who was on a sightseeing trip, not. 

Puzzling, isn't it? I have, as many others, a theory that this was not NCO-level guy, but likely some senior officer and that "testing a new defensive capability" has very little to do with 404 and UK, but likely with "capability" of Russia. These dudes of UK orgs such as Special Boat Service or SAS (and MI6) still think that they play a videogame and that they are still in John le Carre novel about 1980s. I have a bad news for them--Russians know their identities, they know who they are and where to find them. 

As Ron Paul's Institute correctly pointed out:

When you authorize naval-drone terrorism against Russian civilian oil tankers in the Black Sea, don’t whine when Moscow redraws the coastline. You wanted escalation? Fine. Now watch your proxy lose Odessa, and with it access to the Black Sea.

Not only Moscow will redraw  it, but some people may begin to suffer some strange accidents such as falling out of the windows or deciding to end their lives just because. Terrorism does not have statue of limitations, but that is the ONLY capability London has. I speak about it in my today's video about Royal Navy, its submarine "force" and why its delusions of grandeur are a reaction to an ongoing implosion of Old Europe and its becoming a totalitarian concentration camp with no future.
