KUALA LUMPUR, Malaysia (AP) — The Malaysian military has radar data showing the missing Boeing 777 jetliner changed course and made it to the Malacca Strait, hundreds of kilometers (miles) from the last position recorded by civilian authorities, according to a senior military official.

The development injects more mystery into the investigation of the disappearance of Saturday's flight, and raises questions about why the aircraft was not transmitting signals detectable by civilian radar.

Local newspaper Berita Harian quoted Malaysian air force chief Gen. Rodzali Daud as saying radar at a military base had detected the airliner at 2:40 a.m. near Pulau Perak at the northern approach to the strait, a busy waterway that separates the western coast of Malaysia and Indonesia's Sumatra island. "After that, the signal from the plane was lost," he was quoted as saying.

A high-ranking military official involved in the investigation confirmed the report and also said the plane was believed to be flying low. The official spoke on condition of anonymity because of the sensitivity of the information.

Authorities had earlier said the plane, which took off at 12:20 a.m. and was headed to Beijing, may have attempted to turn back to Kuala Lumpur, but they expressed surprise that it would do so without informing ground control. The search for the plane was initially focused on waters between the eastern coast of Malaysia and Vietnam, the position where aviation authorities last tracked it. No trace of the plane, which was carrying 239 people, has been found by than 40 planes and ships from at least 10 nations searching the area.

Earlier Tuesday, Malaysia Airlines said in a statement that search and rescue teams had expanded their scope to the Malacca Strait. An earlier statement said the western coast of Malaysia was "now the focus," but the airline subsequently said that phrase was an oversight. It didn't elaborate. Civil aviation chief Azharuddin Abdul Rahman said the search remained "on both sides" of the country. more
