Mrs. Pratchett

Her name was Mrs Pratchett. She was a small, skinny old hag with moustache on her upper lip and a mouth as sour as a green goosebery. She never smiled.

Her apron was gray and greasy. Her blouse had bits of breakfast all over it, toast crumbs and tea stains and splotches of dried egg yollk. It was her hands, however, that disturbed us most.They were disgusting. They were black with dirt and grime.

And do not forget that it was these hands and fingers that she would plunge into the sweet-jars when we asked for a pennyworth of TreackleToffe or Wine Gums or Nut Clusters, or whatever. There were precious few health laws in those days, and nobody, least of all Mrs. Pratchett , ever thought of using a little shovel for getting sweets out as they do today.

Cuba plane crash: 110 dead as investigators recover flight’black box

The fiery crash of an ageing passenger jet close to Havana’s main airport killed 110 people while three survivors remain gravily in the hospital, making it the Caribean island’s deadliest air disaster in nearly 30 years. The weather was rainy at the airport at the time of the accident and some people could hear a strange noise and saw the plane with an engine on fire. Among the dead are 20 clergy members of an evangelical church, the Mexican pilots and the cabin crew.

PRESSURE

Jeremy Berke

Commercial airplane cabins are generally pressurized to an equivalent of 6,000 to 8,000 feet above sea level, in an effort to maintain a healthy oxygen level for both the passengers and the flight crew. When a passenger jet is flying at a cruising altitude of over 36,000 feet, the pressure outside the cabin is_____________ than inside the pressurized cabin. Air pressure has a tendency to equalize, moving from areas of high pressure to low pressure to achieve equilibrium. When a hole rips open on a plane, the suction resulting from the pressure difference between the cabin and the sky could pull nearby people or objects outside. Depending on the size of the hole, such accidents could either create just enough force to shuffle papers around, or, pull a full-size human out of the plane. Survival is unlikely for anyone fully sucked out into the sky.

While in-flight incidents are extremely rare, if you want to survive a crash, research suggests the best place to sit is in a middle seat toward the back of the plane.
