The speed of light is a constant in all reference frames. So your headlights would shoot out like always. But you have to ignore the fact that matter can't travel at the spped of light - as you get closer to light speed your mass approaches infinity. Plus you get squished in the direction you're travelling. Altogether an unpleasant experience.apemb:

Bird: if the bird moved air downwards, that would be a force acting on the plane, correct? If it were a mass scale,the mass wouldn't change. As a weight scale is really a force scale, if the bird flapped really really hard it might be able to produce a force that would move the plane enough to register on the scale. But probably not, in real life.
burning the plane: all of the metals would melt, the jet fuel would become carbon/carbon dioxide, and water vapor. The water vapor is a gas, and would go through the vents. The carbon dioxide would also esscape. Any "soot" would not. However, some mass has already leftin the form of a gas, so we know the plane will be lighter. Samewith the seats and things, soot would stay but carbon dioxide and water vapor would leave. I think if you supplied it with enough oxygen, you might not have any soot. In this case, the only mass left in the chamber would be the metals.

But what is burning? It's an oxidation reaction. You're adding oxygen atoms to the fuel molecules and releasing heat. It depends on how small the vents are in Andy's enclosure whether the weight goes up or down after burning.JahJahwarrior:

If the bird flies in the plane, remaining airborn, and the doors are closed the weight will increase by the mass of the air displaced by the bird (an imperceptable, but measurable amount). Same goes if you were to hold a goldfish by the tail in the water of a fishbowl, the weight would increase by the mass of the water displaced by the fish.
