Boeing has finished the development of a software fix to its troubled 737 Max. The plane maker said in a statement it has flown the aircraft with the updated software on 207 flights for more than 360 hours. CNN reports that the software heads next to the US Federal Aviation Administration (FAA) and its counterparts in other countries that want to review it. ‘We're committed to providing the FAA and global regulators all the information they need, and to getting it right. We're making clear and steady progress and are confident that the 737 Max with updated MCAS software will be one of the safest airplanes ever to fly,’ Boeing CEO Dennis Muilenburg said in the statement. The 737 Max 8 and 9 were grounded worldwide after an Ethiopian Airlines crash two months ago that investigators have described as appearing similar to a Lion Air crash last year.
