Boeing early last month delivered the first 737-700 Convertible Quick Change aircraft to an undisclosed customer. The 737-700C is the first 737 to be offered in both an all-passenger or all-cargo layout. The Quick Change option is a 737-700C with pallet-mounted seats, reducing the time required for a passenger-to-freighter switch to less than an hour. The 737-700C has the same strengthened wings used on the Boeing Business Jet.
