The beleaguered Boeing 787 Dreamliner could soon return to the skies. The Wall Street Journal reports that the Federal Aviation Administration intends to approve the aircraft as soon as Friday, endorsing battery improvements designed to prevent and contain fires. In February, the FAA denied a previous Wall Street Journal report that it was close to approving test flights, but such test flights did begin in late March, and now it sounds like the Dreamliner might not be the lemon some had feared three months ago.
