Lost Far From A Home

A police car pulls up in front of grandma Bessie's house, and grandpa Morris gets out.
The polite policeman explained that this elderly gentleman said that he was lost in the park...and couldn't find his way home. " Oy Morris ", said grandma, " You've been going to that park for over 30 years ! So how could you get lost ? " Leaning close to grandma, so that the policeman couldn't hear. Morris whispered, " I wasn't lost.....I was just too tired to walk home."

Robert Esnault-Pelterie

Born 8 Nov 1881; died 6 Dec 1957 at age 76.French engineer and aviator who made important pioneering contributions to the beginnings of heavier-than-air flight in Europe. He built a copy of the glider made in 1902 by the brothers Orville and Wilbur Wright. Since he distrusted their steering technique, so he made an innovation by inventing the aileron (a movable airfoil at the edge of the wing). He used a hand operated wheel to control them. Used symmetrically, they provided longitudinal stability. Used differentially, they controlled lateral stability. In 1907, he built one of the first monoplanes, REP-1, more noteworthy for its innovative 7-cylinder radial engine. It was the first plane with a completely enclosed fuselage. His longest flight in this aircraft was only 600 m (2,600 feet). He also invented a new type of fuel pump.
