The Uses of Jets
Today, jet's are a fast, and relatively convenient form of travel. They've changed the transportation industry and are used for everything. Jet's like 747's are used by commercial companies like UPS and FedEx to deliver the mail, and to take people across the world. Every day in just the United States airports, about 29,000 flights take off, and land. Whats more is the US airline industry makesbout a 170 billion dollars in revenue every year. Some jet's are used for private travel, jets like these can cost up to 59 million dollars. Jets are used in the military as fighters, cargo jets, bombers, and can be adapted to many other purposes. Today, flying over the atlanticdd ocean non-stop, in under 10 hours is old news, but less than 80 years ago it was impossible.
