Once had one of my students (72 at the time ) have a full hydraulic failure in a B47G5 whilst out in the training area on his own.
He did as he had been taught and returned to the airfield, conducting only gentle left hand turns and maintaining a steady attitude, placing the machine on the ground next to the runway surface. The hydraulic pump had sheared off at the gears in the engine, thus causing the situation, and had to be replaced.
He spoke about his ordeal for months to anyone that would listen, and got a big Bravo Zulu from the CFI on a situation well handled.
Moral; if a elderly student can handle this type of situation in a old B47, then there is hope for the rest of us!
