Al and Marc welcomed Grant Casstevens of DuPage Aerospace (www.dupageaerospace.com), a Chicago-based charter, maintenance, and aviation management company.  The discussion went way beyond the basic inner workings of the charter business as the guys talked about wild catering requests, unusual passengers, and the daily challenges of running the business.  What a great way to start SimpleFlight's 5th year.  We know you'll love the show. And along those lines, our sincere thanks to all of you for being with us these past 4 years.  We look forward to making this 5th year even better and to keep you as a loyal listener.
