Interesting - I was trying to see who has ever flown a loop in a &$& and this came up...

In any case, this would have been an aileron roll, not a barrel roll...

Ain't happening in real life. That low, anyway...

I met a guy, his name was Hoot Gibson, he flew the sea plane in the last Endless Summer Surf movie. He supposedly did that during his very last flight for I think American, he was dismissed when he landed. The plane only had him and a service crew but that didn't matter, he was gone. he wasn't in a 747, something smaller.

Hoot retired at the mandatory age of 60 from Southwest Airlines after careers in the U.S. Navy and NASA...

I don't think you'd want to do that in a plane like that that low to the ground. I think that without serious thrust to weight or speed, you lose altitude when sideways. But I'm not a pilot, so I could totally be wrong.

Interesting, I'd always thought they were one and the same. Are you saying that a barrel roll involves more of a corkscrew shape/maneuver?

Per Wikipedia:

"Starting from a level flight, the pilot will usually pick such a point on the horizon as a reference, which is typically between the nose and the wing-tip, out the side window (if the plane has side windows). This point can be anything in that area, like a distant lake, mountain peak, or cloud. The pilot will then pull back on the stick, bringing the plane up into a brief climb. As the nose passes through the horizon, the pilot begins to apply aileron input, which is accomplished by easing the stick to either the right or the left. As the airplane rolls it will continue to pitch in the direction of the lift vector. The pilot will need to carefully control the roll rate, keeping the nose 45 degrees off the reference point on the horizon as the nose traces a circle around this spot. Some planes may require rudder input, while most high powered planes will only need to be guided by aileron and elevator control

When the aircraft has rolled 90 degrees, and the wings are vertical, the nose should be angled about 45 degrees directly above the reference point. As the plane continues to roll upside-down it will begin to level out, and the horizon will appear to rise to meet the nose. When in the completely inverted position, the aircraft should be level and the nose should still be 45 degrees to the side of the reference point, putting it 90 degrees off the original flightpath. As the nose drops through the horizon, the pilot may need to reduce the elevator pressure, to avoid altitude loss by counteracting the force of gravity and the loss of lift. Still keeping the nose 45 degrees off the reference point, the plane should roll into level flight along the same flightpath and at the same altitude at which the maneuver began. If properly performed, the reference point should appear to remain in a fairly stationary position, relative to the plane, while the horizon spins around it."

Thanks, it's kind of hard to picture.

Masraum,

I didn't see a good explanation in either of your video's, so I thought I would try to explain the process.

I'm guessing you know this, but to raise the nose of the aircraft (to gain altitude), the aviator pulls back on the stick, to deflect the horizontal stabilizer. To lower or raise a wing one way or the other (to commence a turn), the aviator moves the stick sideways, one way or another, to deflect the ailerons. To do a barrel roll in its simplest form, the aviator pulls back on the stick and deflects it one way or the other in equal amounts. Meaning, the amount he pulls the stick back equals the amount he moves it to the side. You continue this equal pull/deflection to a point, holding the position until you go from straight and level flight, rolling through being inverted, and rolling back around towards normal flight. As your nose and wings are coming around to straight and level flight, you ease the stick back to its neutral position and you should end up at around the same altitude and within a few degrees of the same direction you started. A good pilot would match the entrance and exit numbers...
