In Switzerland, an Opel delivery van had to be airlifted from a mountain, following a navigation error by its driver. The driver followed the directions given by his satellite navigation system, which told him to follow a narrow track that wound slowly upwards. Trusting his GPS system, the man drove as directed up the narrow pathway until the vehicle could move no further. The van finally became firmly wedged between a fence and a stone wall and unable to turn around or reverse, the driver called the emergency services. They provided a helicopter to remove the van. However a local fireman praised the driver's off-road skills in negotiating the goat track in his Opel van.
