For the plane breakdown part. UPS has Planes and crews ready to leave within 30 minutes if the need arises they are called Hot Spares.Yeah it was planned, but to me it always feels like they are not playing it very safe. I mean what if a storm blows up, a plane breaks down, aliens invade and are found to subsist on spoiled milk and iPhone parts? Stuff could happen...if I were in charge I would want the packages at the Louisville hub asap instead of letting them sit for a day somewhere in China or S Korea.
