(Everett, WA)  --  Boeing is considering halting production of its iconic 747 jet.  Company officials told the Everett "Herald" that new technology, changing travel patterns, and economics have diminished the need for the world's first jumbo jet.  Boeing says waning demand for the 747 was a contributor to the company's second-quarter loss, its first quarterly loss in nearly seven years.  More than 15-hundred 747s have been built since the jet debuted in 1970.
