Yesterday, it was a fuel leak on a 787 Dreamliner taking off from Boston. The day before, it was an electrical fire aboard a Dreamliner that had just landed in Boston from Tokyo.

The events were the latest in a series of problems with the 787, which entered commercial service in November 2011 and has been hit by technical and electric malfunctions since then.

Among the previous problems: a mid-flight generator failure in December, and a warning from the FAA (also in December) about fuel line connector problems on the plane that could pose "a risk of fuel leaks and fires." Yikes.
