Jatropha curcas, is a perennial poisonous shrub, Barbados nut or Physic nut with a height of up to 5 meters.
The plant originating in Central America, and it has been spreead to other countries in tropical ang sub-tropical countries as well and is widely grown in Asia and Africa. It is an uncultivated wild species, a non-food plants. In the Philippines it is widely use as a living fence to protect the gardens and any other fields from animals, it is also use believed as a deterent to snakes, it grows in desert and even grow with less water and as such does not compete with food crops, the animals don't like to eat the leaves so they can grow well.
The seeds contains 30% oil that can be process to produced high quality bio-diesel fuel, usable for a standard diesel engine.
We try to plant Jatropha curcas, but the problem is the market. There is no known market yet in the Philippines, so we stop planting Jatropha, in the bakyard of our house Jatropha is a common plant.
Early reports suggest that a bird strike caused a jet plane to crash in the Hudson River near Manhattan today, leaving questions about how a little flying animal could down a big airliner.
More than 200 people have been killed worldwide as a result of wildlife strikes with aircraft since 1988, according to Bird Strike Committee USA, and more than 5,000 bird strikes were reported by the U.S. Air Force in 2007. Bird strikes, or the collision of an aircraft with an airborne bird, tend to happen when aircraft are close to the ground, which means just before landing or after take-off, when jet engines are turning at top speeds.
The incidents are serious particularly when the birds, usually gulls, raptors and geese, are sucked into a jet engine and strike an engine fan blades. That impact displaces the blade such that it strikes another blade and a cascade can occur, resulting in engine failure. Geese or another large bird would be much more hazardous than a little black bird. If the birds get close to the engine's intake, the birds get sucked in, its like a vacuum. The jet engine are made up of a lot of compressor blades it can easily damaged, even if only one breaks off, then the one blade will go through the rest of the engine as the engines turning faster its like a sharpnels inside the engine.
A 12-pound goose striking an aircraft going 150 mph at lift-off generates the force of a 1,000-pound weight dropped from a height of 10 feet, according to Bird Strike Committee USA. Birds can be very dangerous to aircraft, particularly in the first several thousand feet after take-off, where the birds are flying.
Large aircraft are certified to be able to keep flying after impacting a 4-pound bird, however if there are more that one 4-pound birds, even smaller birds, can cause engine failure.
The greater the difference in the speed of the plane and the bird, the greater the force of the impact on the aircraft. The weight of the bird is also a factor, but the speed difference is a much bigger factor.
The speed at which the two are moving causes the bird to get ingested into the engine. And the engine is very delicate to withstanding a major impact and shut the engine down.
Flocks of birds are even more dangerous as they can result in multiple strikes.
Delicate birds, delicate aircraft
