For those with a passion for aviation’s quietest, most graceful pursuit, it’s akin to a type of nirvana. To enter the Gliding Heritage Centre is to walk into a treasure-trove, decades of silent flight history laid out in front of you, different shapes and colours abounding. Its status in the museum pantheon, what’s more, is not in doubt. One could debate for hours which of the big national aircraft collections, or which of the major independents, is the best. By contrast, in its specialist field, there is nothing whatsoever to touch the GHC. Beyond that, it ranks among the largest airframe collections in Britain, and many of them still fly.
