They are called "dancing diamonds" and are formed when the pilot initiates the afterburners and are formed when the exhaust (flames) travel at above supersonic speeds.
Yes
To use afterburners in Microsoft Flight Simulator X, apply full throttle.
The obvious answer is, until it runs out of fuel. If immediately after takeoff the pilot used his/her afterburners they would have about 7 minutes max.
Most modern fighter jets max out at about 2 or 2 and a half times the speed of sound. Most aircraft however cruise at subsonic speeds (under the speed of sound) so that they don't need to use afterburners which guzzle down fuel. That's changing however with the F-22 and latest Russian fighters being able to sustain supersonic flight (supercruise) without using afterburners.
The fly and then they shoot (:
about 1.7 mach without afterburners with afterburners 1,317 mph over 2 mach (1 mach speed of sound about 680 mph
It's specified Max. Speed is mach 2.25 (1,500 mph, 2,410 km/h). It is the first fighter aircraft to achieve supersonic speeds without afterburners. (Mach 1+ without afterburners).
Overdrive afterburners, and supersonic flight capability- It is, alas, obsolete.
Jets need air in order to work. Look at the jet engines on an airliner, and you'll notice that the front of the engine is wide open . . . to take in large gulps of air and mix it with the jet fuel. There's no air in space, so jets don't work there.
Jets.
No. Gliders, jets and rocket-propelled aircraft do not have propellers.
