The 19th Air Force has indefinitely suspended all solo flights in T-6 Texan trainer<\/a> aircraft \u2015 both for students and instructor pilots \u2015 over concerns about hypoxia<\/a> and other so-called unexplained physiological events.<\/p>\n\n\n\n

A screenshot of a message posted early Wednesday on the unofficial Facebook page Air Force amn\/nco\/snco<\/a> also said that Maj. Gen. Patrick Doherty, commander of the 19th Air Force, has authorized all T-6 instructor and student pilots to fly with their masks down \u2015 that is, with one bayonet, or connector, unlatched. This is so they can breathe cockpit air to lessen the risk against hypoxia and related problems, and will be allowed both on the ground and in flight.<\/p>\n\n\n\n

\u201cDue to the nature of T-6 Unexplained Physiological Events (UPE)<\/a> symptoms and ability to recognize the situation, all solo sorties (both student and IP) are suspended until further notice,\u201d the message said.<\/p>\n\n\n\t
