I cannot think of a civil airliner where the nose gear retracts backwards - they all retract forwards.

Well, the deHavilland Dash 7 has one, and I will take exception to anyone denying it airliner status.

A small handpump is used to ensure downlock after freefall extension. (The Dash 8 and Fokker 50 have - much larger and draggier - backwards retracting main gear, assisted by handpump and springloading respectively for downlock after emergency freefall extension.)

Thanks to all Concorde experts for this truly wonderful thread. The ingenuity of design and the complexity of design that enabled the technological marvel that is Concorde never cease to amaze this humble airline driver. Having missed the opportunity to fly on Concorde is high on my list of aviatic regrets as well, and I'll have to make do with the memories of watching Air France Concordes taking off from CDG during our turnarounds there.

I could (and actually have) spent hours following this thread.

Is it true that Concorde was always flown by the highest seniority BA captains, copilots and flight engineers? Would Concorde usually be the last rung on the ladder before retirement for Captains/FEs or was it usual to return to slower equipment after a stint on Concorde?

And, sorry if I missed this, would Concorde thrust levers move during autothrottle operation?

Lastly, Concorde was originally to have had a large moving map system. Any insights into why and how that got scrapped along the way?

Thanks!

I don't know whether the shuttle tyres are actually reused or not, but if a remember right, the side wall printing says good for 12 uses.

Given the frequency of Shuttle sorties 12 landings would mean a lifetime longer than most airline tires, at least if expressed in years.

Here is the page with all the journals just in case the above does not work (did not work for me). Fascinating Reading.

There are various sources on the web that claim varying Mach/supersonic time restrictions for the the Pepsi-branded Concorde, mainly based on the inability/reduced capability of the dark livery to "deflect heat". This seems a bit strange given the black paint of the SR-71 and I'd appreciate comments by anyone in the know about this.

Is that an air brake on one of the prototype aircraft?

Probably a braking chute housing/door. Looks a bit like the one around 2:50 into this video. (Turn down the volume.)
