Avioneta que no responde a las llamadas de radio entra en el espacio aéreo cubano.

http://www.cnn.com/2014/09/05/us/norad-air-threat/index.html?hpt=hp_t1 A Cuban fighter jet Friday was trailing a small aircraft that was unresponsive over the Atlantic Ocean and flying over Cuban airspace, NORAD said. The U.S. military launched a pair of jet fighters to trail the aircraft, but the U.S. planes broke off before reaching Cuban airspace 12 miles off the islands coast, NORAD said. The plane was cruising at about 25,000 feet. Ted Soliday, executive director of the Naples, Florida, airport, where the plane was headed, told CNN that he did not know how many people are on board the six-seat aircraft. Its believed the plane could be running out of fuel.

Most recent flight path "Once it gets up that high, it can cruise at good speed with low fuel use," he said. "Five hours is a long time for that airplane." Two F-15s had been flying with the plane east of Florida. The windows, according to a NORAD spokesman, were frosted and it was unknown how much fuel was left. NORAD was in touch with Cuban authorities via the U.S. Coast Guard. The U.S. military jets will not enter Cuban airspace, a NORAD spokesman said. The Socata TBM-700 light business and utility aircraft departed from Rochester, New York, with a flight plan to land in Naples, NORAD said. But the planes occupants did not respond to communication attempts. 2012: Small plane with unresponsive pilot crashes

El Instituto de Seguridad Aérea de la AOPA ha emitido una recomendación a raíz de este accidente y otro sucedido el 30 de Agosto. Se recomienda el uso de un "Oximetro de Pulso" (Pulse Oximeter), el cual mide de manera indirecta la saturación de oxigeno de la sangre de una persona. Esto es para todos aquellos pilotos que vuelen en cabinas no presurizadas por arriba de 10 mil pies. La publicación la pueden encontrar en este enlace

No sería mala idea que el oxímetro también mandara una señal de alerta al control de vuelo poco antes de acercarse a niveles peligrosos para que se comunicaran con el piloto y saber si hay problemas.
