"There are around 30,000 commercial flights per day over the U.S.," says Casaretti. "If you were to attempt to place a team of just two FAMs on each flight, it would require an agency of over 75,000 FAMs (accounting for training and days off). FAMs cover a very small percentage of commercial flights."
- John Casaretti, National President of the Air Marshal Association/CWA.
"If one accounts for vacations, sick leave, medical leave and days off, some air marshals working in operations have told me that this accounts for less than one half percent of all U.S.-flagged aircraft being covered by federal air marshals"
- Clay Biles, a former Navy SEAL who spent five years as a federal air marshal and is the author of a book about FAMS called Unsecure Skies.
