Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Turbine max speed is 11rpm, that's a speed of 48.4 m/s at a radius of 42 m (where the A380's center of gravity should pass). At the same radius, the free space between two blades should be about 85-86 m. Subtracting the A380's fuselage height of 8.41 m, I get a possible passage time of 1.6 seconds. With the A380's length of 73.73 m, you'd need a speed of at least 165 km/h to pass. Even minimum takeoff speed (about 250 km/h) is above, so the A380 wins :-)

Yes, as long as the Rolex used to time the entry point is working properly.  ;-)

Reminds me of the question I asked of an ex-Air Force, United Airlines training pilot: "Can you barrel roll a 707?"

Answer: "Uh, I would rather not say."

Well, I once wrote a short story in which a passenger took the commands of a Boeing 777, after hijackers killed both pilots. He had extensive experience with MS Flight Simulator, you see, so he knew exactly how hard you could push it without tearing the wings off. He flew it down into the Grand Canyon, then under the Golden Gate bridge, then headed for a disused airstrip in Kamchatka.

But he had never bothered learning to land the thing.

A barrel roll is supposedly  a stress free manouevre, so it should be okay.

Concorde could barrel roll.

Exactly. But the only way to find out is to try it.

My experiences with perhaps a dozen ex-military pilots who went into the commercial airline business makes me think that passenger jets were routinely rolled. Back in the days before every single thing that you do is recorded. Probably not any more.
