My friend went on to write, "but then when in the air, and the helicopter flies a circuit over the village, the helicopter has the addition of bouyancy floats!" And here is a picture of that helicopter.
It was well observed. And when I replied to my friends letter, I congratulated him upon his observation. But what he had failed to observe, is that these are two different helicopters! And that when the helicopter lands back outside the Recreation Hall, it has reverted back to being the one in the top picture. The bottom picture is merely from stockfootage of the original village helicopter, filmed at Portmeirion. While the helicopter seen taking off outside the village Recreation Hall, was filmed on a back lot at MGM film studios at Borehamwood.
Be seeing you
