It is early in the morning 9 am, fast jet action began with four pairs of Northrop F-5E Tiger II from Fliegerstaffel based at Meiringen. Flying figure-of-eight patterns, the F-5E pilots attacked targets set up on the mountainside from all four points of the compass. With short bursts from the two nose mounted 20mm M39 cannon, they fired at the pairs of 6m wide orange cloth targets. When flying across the narrow valley, the jets approach the shear mountainside and pull up into a steep climb and pass inverted over the mountain peak, this is truly breath taking.
