Propulsion is what keeps a jet in the air. Otherwise the plane has to fall down. Propulsion keeps the air always flowing over the wing which in turn keeps the plane afloat.
A Scram jet is a jet which needs supersonic propulsion to take off. It is taken into air by another larger aircraft and is released in supersonic speed.
Ramjets work with an air intake speed of, usually, 400mph+ but scramjets require supersonic air speed to function.
It depends on the model of the Royal Air Force fighting jet that you are asking about. But the Eurofighter Typhoon jet, has a top speed of 1,320mph.
It depends entirely on the speed of the jet.
280kmph.
Jet streams gain speed due to the temperature and pressure differences in the atmosphere. As air moves from areas of high pressure to low pressure, the Coriolis effect causes it to deflect, creating a fast-moving band of air called a jet stream. Additionally, the presence of the polar front jet stream at the boundary of cold polar air and warm tropical air can also contribute to high wind speeds.

Jet Streams
A jets take of speed is dependent upon the weight of the jet and its cargo. The average take of speed for a Boeing 707 is 150 miles per hour.
Pilots often take advantage of jet streams. If going in the same direction, jet stream can add up to 200mph to their ground speed.
it depends what jet.
According to the Encyclopedia of World Air Power the fastest fighter jet is, The F15: Mach 2.5, approximately 1,400 mph.
