The Boeing 787 Dreamliner carries special importance for Boston, since it’s the only plane capable of taking off fully loaded for Asia from Logan Airport’s runways. It opens Boston to half the world — but not until its dangerous electrical woes are resolved.

In retrospect, the spate of incidents — including the battery fire earlier this month on a Japan Airlines plane at Logan and culminating in an even more serious battery problem on an airborne Dreamliner in Japan — provided valuable warnings. No one was injured, but the sheer number of problems entirely justified the decisions of US and Japanese authorities to ground all 787s immediately.
