Cuenta atrás para el primer salto en caída libre desde la estratosfera

Martes, 2 de octubre de 2012 Jose María Pérez Sastre Sin comentarios

El saltador Félix Baumgartner se convertirá, el próximo 8 de octubre, en la primera persona en superar la barrera del sonido sin apoyo mecánico. El austríaco viajará a la estratosfera terrestre en una cápsula presurizada y se lanzará en caída libre desde 36.576 metros de altura. Con el salto se intentarán batir hasta cuatro récords: mayor velocidad en caída libre, salto de mayor altitud, vuelo en globo tripulado de mayor altitud y caída libre más larga.

 

** Estaremos muy atentos al desarrollo de esta haza√Īa:

How often do plane stowaways fall from the sky?

Lunes, 17 de septiembre de 2012 Twitter Sin comentarios

Police are investigating whether a man found dead on a west London street was a  stowaway who fell from a plane. No-one saw the body fall from the sky on to Portman Avenue. It is not the first incident of this kind on the Heathrow flightpath.  Dr Stephen Veronneau, of the US Federal Aviation Administration, has identified 96 individuals around the world who have tried to travel in plane wheel wells since 1947. The incidents happened on 85 flights. Veronneau is working on the assumption that the Mortlake fatality was a stowaway. Of these, more than three-quarters have proved fatal.

This article answers following questions : Just how often does this happen and what are the riks?

USAF vows to discover root cause of Raptor’s maladies

Miércoles, 4 de abril de 2012 FSI / Curt Lewis Sin comentarios

Air Force leaders provided an update on the Air Force Scientific Advisory Board study into the F-22 Raptor life support systems. From April 2008 until May 2011, the Air Force experienced 14 physiological incidents with the fleet of F-22s, noticed a pattern of unexplained hypoxia-like physiological incidents. The USAF¬†have taken precautionary measures such as installing activated-charcoal filters, oxygen sensors, and having pilots wear a pulse-oximeter. But despite the “mitigation efforts,” there continues to be incidents recorded every month.

The malinois: “Parachutist dogs”

Martes, 3 de enero de 2012 Twitter Sin comentarios

German shepherds are still used as war dogs by the American military but the lighter, stubbier Malinois is considered  better  for the tandem parachute jumping and rappelling operations often undertaken by SEAL (sea, air and land) teams. Labrador retrievers are also favored by various military organizations around the world.  Last year canine parachute instructor Mike Forsythe and his dog Cara set the world record for highest man-dog parachute deployment, jumping from more than 30,100 feet up. Here you can see a beautiful presentation that was taken directly from an email that is jumping from computer to computer without no master.¡ Let us Enjoy it ¡

Verge of Consciusness (The threat of Hypoxia)

Viernes, 9 de diciembre de 2011 Jose María Pérez Sastre Sin comentarios

An improperly adjusted safety switch that rendered the aircraft’s pressurization system inoperative, an incorrectly wired cabin altitude warning switch that disabled a warning light and the pilot’s ineffective systems monitoring while distracted by an autopilot problem early in the flight were among the factors that led to a dangerous encounter with hypoxia, according to the Australian Transport Safety Bureau (ATSB). According to the safety report there is a continuing concern about hypoxia incidents especially in single- pilot, turbine-powered, pressurized aircraft.

“Polizones a√©reos: Un alto precio por la libertad”

Ayer en Barajas fue hallado muerto en el tren de aterrizaje de un A340 de Iberia procedente de La Habana un joven de 23 a√Īos y nacionalidad cubana, que emulando a su compatriota Armando Socarr√°s ¬†inici√≥ un vuelo hacia la libertad con un coste demasiado alto. Ten√≠a heridas en el t√≥rax y en la cabeza y pudo haber fallecido por cualquiera de los riesgos inherentes a estos vuelos, incluido por supuesto la hipoxia. Seg√ļn datos de la FAA, desde 1947 hasta 2007 han ocurrido 74 casos con una supervivencia de¬†14 casos (19%).

¬Ņ Sabes …por qu√© hay aves que pueden volar a 10.000 m de altura?

Seg√ļn escribe Juan Ignacio Perez en el blog “Animaladas”, “los p√°jaros se pueden desenvolver con relativa facilidad en alturas de hasta 6.000 m, gracias a la especial estructura y funcionamiento de su aparato respiratorio y al tama√Īo de su coraz√≥n. A esa altura hay muy poco aire y, por ello, muy poco ox√≠geno, pero los sistemas cardiovascular y respiratorio de las aves son muy eficaces. En 1977, por ejemplo, un buitre de la especie Gyps rueppellii, choc√≥ con un avi√≥n que volaba a 11.277 m…

Qantas Flight QF30 Rapid Depressurization

Jueves, 3 de febrero de 2011 Esther Felipe Duyos Sin comentarios

The Boeing 747-100 operated by Qantas Airways as Flight QF30 departed from Hong Kong international airport to Melbourne on July 25, 2008. When it was cruising 29.000 ft over the South China Sea, one emergency oxygen cylinder burst and ripped a hole through the right side of the forward cargo hold. The flight crew conducted an emergency descent and landing to Manila. Damage to the airliner was substancial but none on board was injured. Here in attached you can read interesting article about it. Though this type of accidents are becoming less frequent, we should not overlook real cases like this to improve our knowledge on this key safety matter
