Both groups do really great work, and neither one will release any of your personal information to anyone or any company (read FedEx) without your specific approval. That approval is done in writing, by you, before they can release your data. Although Dr. Kendall's group is paid by FedEx, they are there for you, to, in some required cases, act as a go-between between you and the FAA. I worked with them a number of years ago and they did wonderfully on my behalf.
