For employment with the Firestorm Smokejumpers—a crew of elite paratroopers who parachute into dangerous situations to fight fires—applicants must complete a series of tests. The crew chief sends the most qualified applicants a letter stating that they will be admitted to Firestorm's training sessions if they pass a medical exam. Jake Kurzyniec receives the letter and passes the exam, but a new crew chief changes the selection process and rejects him. Is there a contract between Kurzyniec and Firestorm? If there is a contract, what type of contract is it?
