Visited Le Radôme near Lannion (Brittany), the largest inflatable structure in the world (50 meters) – a 2mm parachute covering 1 hectare, weighing 27 tons itself + 6 tons of paint, with a rotating antenna on rails inside, from 1962, weighing 350 tons. Made the first direct video broadcast from Europe to the USA via satellite, where a similar device existed (the Americans dismantled it). Cryogenic signal receiver, minus 261°C. Inside the sphere, the pressure ranges from 4 to 12 millibars. The youngest national monument in France.
