You don't have to wait for an internship to come to you. Purdue is an NBAA member allowing you access to the online directory. Draft a letter to flight departments that interest you and offer your internship services to them. You will at least have the experience of contacting flight department managers. Don't overlook management companies and charter operators. Nothing in corporate aviation is going to find you, you have to politely and professionaly find it.

Good Luck
