When the jet is pointed almost directly at us, and it is traveling at nearly light speed, it will get to the nearer point only slightly behind the light from the farther point. On arrival at the nearer point, light will be immediately emitted due to impact of the beam on matter at that point. That secondary light will thus only be a little behind the light from primary event, and thus appear to us to be related to it more closely in time than the actual distance would allow. >Most reports of superluminal effects are not hard to debunk.
