All papers wrote today that a test flight to the U.S. by Mitsubishi Regional Jet (MRJ) was aborted on Sunday for the second consecutive day due to problems with the plane’s air-conditioning system. The aircraft, which is Japan’s first domestically developed passenger plane in more than half a century, returned to Nagoya on Sunday afternoon after a two-hour flight. The dailies expressed concern that the mishap will raise doubts among potential customers about the plane’s reliability.
