If you could fly any prototype or drawing board design aircraft which would you pick?

Hello there IFC!
At some point many of us have been asked what aircraft you’d like to fly. Today though, hypothetically, if you could fly any aircraft prototype or an aircraft that never left the drawing board or was cancelled before the prototype could be built, which one(s) would you pick?

For me, I’d have to go with the Lockheed L-2000, basically the Lockheed Concorde, or the VTOL jet transport, Dornier Do 31.

I did try putting this up in the RWA category about 24hrs ago, but it didn’t seem to work and I can’t find it anywhere, so here’s take two.

Either the Lockheed XB-70 or the Boeing 2707.

Or the Avro Arrow.

Or a Lun-Class Ekranoplan.

Hey!

Mine would be the Boom Supersonic Overture.

If your topic wasn’t posted in #real-world-aviation, it means that the mods have either not gotten a chance to look at it yet (in which case, just be patient), or the topic has been rejected for a good reason.

#general is a category for things related to Infinite Flight which don’t fit into any other category. Not an “alternative” to RWA. Just something to keep in mind. :)
