A massive international sea search has so far turned up no trace of the jet, though Vietnamese authorities said late yesterday that a low-flying plane had spotted a rectangular object in waters about 90 kilometers (56 miles) south of Tho Chu island, in the same area where oil slicks were spotted Saturday. Search teams from Vietnam and other countries were asked to send boats to the area to examine the object. Authorities said earlier that they had spotted an orange object in the area that turned out not to be from the aircraft.
Airplane crashes typically occur during takeoff and the climb away from an airport, or while coming in for a landing, as in last year's fatal crash of an Asiana Airlines jet in San Francisco. Just 9 percent of fatal accidents happen when a plane is at cruising altitude, according to a statistical summary of commercial jet airplane accidents done by Boeing.
Capt. John M. Cox, who spent 25 years flying for US Airways and is now CEO of Safety Operating Systems, said that whatever happened to the Malaysia Airlines jet, it occurred quickly. The problem had to be big enough, he said, to stop the plane's transponder from broadcasting its location, although the transponder can be purposely shut off from the cockpit.
