1. 1 Medium

   What raised at Mach 2 to protect Concorde's cockpit glass?

   Answer: Visor

   Why: Specially tinted, heat-resistant glass in the visor allowed pilots to see ahead while blocking high-altitude friction heat.

2. 2 Easy

   What category of airliner was Concorde?

   Answer: Supersonic

   Why: Concorde and the Soviet Tu-144 remain the only supersonic airliners to have ever carried paying passengers on scheduled routes.

3. 3 Medium

   What happened to Concorde's length in flight?

   Answer: It grew longer

   Why: Friction from supersonic air heated the plane's skin above 100°C, stretching the metal body by nearly 30 centimeters.

4. 4 Medium

   What metal made up most of Concorde's airframe?

   Answer: Aluminum

   Why: Aluminum alloy was easier to manufacture than titanium, but friction heating on the metal set Concorde's speed limit near Mach 2.

5. 5 Medium

   What gas inflated Concorde's tires to prevent landing fires?

   Answer: Nitrogen

   Why: Brakes reached around 500°C on touchdown, making inert nitrogen essential to keep tires from exploding in flames.

6. 6 Medium

   Why was Concorde painted almost entirely white?

   Answer: To reflect heat

   Why: When one Concorde was painted Pepsi blue in 1996, pilots had to limit high-speed cruising to stop the skin from overheating.
