While wandering around a small village near Bern with a local, I was shown barriers across the road that could be closed in seconds, a small hard standing in front of a windowless building large enough for an aircraft, even down to the taxiway centreline leading onto the road.
It was also mentioned that the "road" was not of usual construction but was constructed and finished to support operations. Many locals were reservists and could be very quickly mobilised. Very cunning these Swiss.
