Well, they may never take the place of powder, but damn, railguns sure do look good when they're fired. Like Glenn, I got nothing on what seems to be some sort of plasma trail behind the round. Maybe at those speeds it just burns the air?

Update: AvWeek watched it live.
I don't think that's the air; I think that's the aftermath of the projectile hitting a target (steel plate) and punching through. If you look at some of the "in flight" shots you don't see anything behind the projectile.
