Boeing Co.’s newest plane, so big that its wings are hinged, finally rumbled into the skies over the Washington factory complex constructed a half century ago for the original jumbo jet.

After a delay Friday because of high winds, the jet took off from Boeing Field at 10:09 a.m. PST Saturday and landed successfully almost four hours later. It’s set to fly again on Tuesday and undergo tests for as long as 10 months.
