There are concerns over Taiwan's Penghu Islands' area that is the Asia's Bermuda triangle. During a routine training mission a fighter jet disappeared some days ago.
Experts say the irregular magnetic field breaks navigational devices, but this was rejected later. In two decades three commercial airplanes, a civil helicopter and five fighter jets crashed.
In 2002 an airplane broke into four parts, and all the 225 passengers aboard died. Later at the same place a cargo plane crashed. The County chief of Penghu blamed the big air traffic over that area. He said human or mechanical failure the cause.
