The term jet lag was created after the arrival of jet aircraft, because prior that it was uncommon to travel far and fast enough to cause the condition. [4]

For example, entrainment is manifested during travel between time zones, hence why humans experience jet lag. Biological rhythms are endogenous; they persist even in the absence of environmental cues as they are driven by an internal mechanism, the circadian clock being the best characterized.
Jet lag has been experienced by passengers traveling from the east coast of North America to the west coast of South America, or vice versa, which is a very long flight, but only one time zone.

The type of jet engine used to explain the conversion of fuel into thrust is the ramjet.It is simpler than the turbojet which is, in turn, simpler than the turbofan.It is valid to use the ramjet example because the ramjet, turbojet and turbofan core all use the same principle to produce thrust which is to accelerate the air passing through them.
