That's what word about town says they have/do. I used to live in Denver and I heard it several times from their former employees, it's what they apparently do enough to generate the reputation.

Be that as it may, my advice to anyone looking at a pilot training contract is, take a hard copy of it to your lawyer (see contract law in the local phone book) and ask what happens if the employer fires you for any reason. What are your legal options if that happens. If the employer refuses to allow you to take a hard, unsigned copy of the contract for this purpose, walk away from the job.
