We have, apparently, more than 40 museums dedicated mainly to flight. Two of my own favourites, Brooklands and Old Warden, also have substantial collections of things without wings.

We're particularly lucky that there are so many people committed to not only preserving these treasures in museums (it is astonishing how many experimentals
are preserved at Cosford, at Newark, Duxford, Yeovilton and elsewhere), but showing dedication above and beyond in getting these beauties back into the air. I know we're not unique, The Netherlands has an enthusiastic warbird community, the Americans ..... well, they do it BIG as you'd expect and what they are doing down in New Zealand is mind boggling.
Many of these aircraft are 70, 80, 90+ years old yet we're seeing more of them in the air, not less. Not so long ago we had no airworthy Mosquitos anywhere, now there are four with more under restoration; we should see a Tempest II back in the air very soon, and there are five more being restored (wo more Mk IIs and three Mk Vs), there are three teams looking to get Typhoons back into the air, there are three Brisfits (and Peter Jackson has another in storage) ....... I'm gobsmacked and very, very grateful.
