Renewal is possible in two days by FedEx, for an extra hefty fee.
For pilots that are too cheap...wait longer.
NB.
One of our pilots renewed his passport in one day, by traveling directly to the local US State Department passport office....with photo in hand.
Cost was $289, as I recall, for super expedited service.
Local Passport Offices are listed on line, or...in the telephone directory (the latter if you are lucky).
