The GR 5 is a GR footpath that crosses France from north to south. It is part of the European walking route E2. This trail is famous for crossing the French Alps form the lake of Geneva to Nice.
The Harrier GR5, GR7, GR7A, GR9 and GR9A are all Royal Air Force variants of the BAE Systems/Boeing Harrier II.
With the retirement of the Sea Harrier it has been suggested that its Blue Vixen radar could be transferred to the GR9 fleet however the Ministry of Defence has rejected this as risky and too expensive, Armed Forces Minister Adam Ingram estimated the cost would be in excess of £600m.
The first BAE built development GR5 flew for the first time on April 30, 1985 and the aircraft entered service in July 1987.
The GR5 begins at Hoek van Holland on the North Sea, and ends in Southern France at the Mediterranean.
Probably, this is because they want to be walking from the the cold, rainy, grayer weather of Holland to the warm, dry, sunny Mediterranean; and also, to finish up their trip with the excitement of the Alps and a Mediterranean arrival.
Rivers draining the Alps along the French border flow to the west, that is, across the grain of the north and south running GR5.
