Dreamliner jets will not fly again -U.S. Transportation Secretary
Jan 18 (Reuters) - U.S. Transportation Secretary Ray LaHood said on Friday that the Boeing Co 787 Dreamliner jets will not fly again until authorities are "1,000 percent sure" they are safe.
He said authorities must first fully investigate the batteries linked to recent incidents, and he could not predict when flights would resume.
The U.S. Federal Aviation Administration on Wednesday temporarily grounded the 787 after a second incident involving battery failures caused one of the Dreamliner passenger jets to make an emergency landing in Japan.
The grounding came less than a week after Boeing and U.S. federal authorities reassured the public of the safety of the new-generation plane.
During a press conference last week LaHood went as far as to say he would have "absolutely no reservations about boarding one of these planes and taking a flight."
When pressed by reporters on Friday about whether he regretted his prior statements, LaHood said, "Last week it was safe."
What has changed since then, he said, is the fact that another incident occurred involving the lithium-ion battery installed in 787s. Such batteries pack more energy and weigh less but are also potentially more volatile.
