Years ago ( mid 80's) while on company trip to Switzerland, several us us were on a tour bus heading up towards Interlachen. We were wind our way along those narrow, picturesque 2 lane Swiss roads. All of a sudden, traffic is stopped ahead. We're alongside a good sized, but flat meadow, and we notice what appears to be a runway in the middle of it, but nothing else. Suddenly, the side of the mountain swings open..and THREE Mirage fighters rolled out onto the runway and took off, one after the other. I swear the whole thing, from the mountain opening, to the planes taking off, and the mountain closing, was over in less than TWO minutes. Then the traffic just moved off.
One would think that the Swiss would want to physically hold their own gold.
