Thousands mourned on April 4 the assassination1 of civil rights leader Martin Luther King 40 years ago, but embraced a recommitment to his dream of equality.
"We are here because destiny has drawn2 us here," his youngest daughter, Reverend Bernice King said as she addressed a huge crowd at the spot where he was shot to death at the Lorraine Motel in Memphis, a day after rallying striking sanitation3 workers.
King's son Martin Luther King III proposed to hold a march on Washington this year similar to the historic gathering5 his father headed in 1963.
That was when he delivered his landmark6 "I Have A Dream" speech that galvanized the civil rights movement with a message of equality and non-violence.
Five years later, at just 39, he was shot dead while he was standing7 on the balcony of the Lorraine Motel on April 4, 1968.
First hydrogen-battery powered plane flown in Spain: BoeingU.S. aircraft giant Boeing claimed on April 3 a world first in putting into the air a plane powered by a hydrogen-cell battery, a breakthrough that could herald8 a greener future for the industry.
"For the first time in the history of aviation, Boeing has flown a manned airplane that was powered by a hydrogen battery," Boeing chief technology officer John Tracy said.
Boeing staged three successful test flights of the 6.5-meter long plane in February and March at an airfield9 at Ocana, just south of Madrid.
The company said that although hydrogen fuel cells could be used to power small planes, it did not believe they could become the primary power source for large passenger aircraft.
Hydrogen power uses "fuel cells" that tap the energy produced from the chemical transformation10 of hydrogen and oxygen into water.
