There were no voice communications related to the crash of Air France Flight 447 last Sunday evening. But a spurt of telemetry data received from the four-year-old Airbus A330 indicated at least a dozen system failures, including loss of electrical power and pressurization. All 216 passengers (from as many as 32 different countries) and 12 crew members are presumed lost, and search aircraft have located a debris field extending some three miles along the ocean surface. Two Americans were reportedly listed on the passenger manifest. The airliner was about four hours into the flight from Rio de Janeiro to Paris and was cruising at 35,000 feet over the Atlantic, approximately 400 miles off the coast of Brazil.
