You guys know what?
There was an episode in Avengers, with John Steed and Emma Peel, "Two's a Crowd" in 1966,
where a guy they want to meet is shot at a lake by a remote control submarine!
Somehow, this little grey ugly duckling remembers me of that scene!
Actually, thinking about it...that scene possibly has triggered my interest in ship models...
(Well, Diana Rigg for sure initiated my interest in other important things in life!

)
He he!
Cheers!
