KUALA LUMPUR, Malaysia - An Australian search and rescue official says that planes have been sent to check on two objects possibly related to the missing Malaysia Airlines flight that were spotted on satellite imagery in the Indian Ocean about 2,500 kilometers (1,550 miles) southwest of Perth.

But John Young of the Australian Maritime Safety Authority cautioned Thursday against expectations that this may help solve the mystery of the plane that went missing with 239 people on board nearly two weeks ago.

Young told reporters, "We have been in this business of doing search and rescue and using sat images before and they do not always turn out to be related to the search even if they look good, so we will hold our views on that until they are sited close-up."

The hunt for the Boeing 777 has been punctuated by several false leads since it disappeared March 8 above the Gulf of Thailand.

Oil slicks that were spotted did not contain jet fuel. A yellow object thought to be from the plane turned out to be a piece of sea trash. Chinese satellite images showed possible plane debris, but nothing was found.

But this is the first time that possible objects have been spotted since the search area was massively expanded into two corridors, one stretching from northern Thailand into Central Asia and the other from the Strait of Malacca down to southern reaches of the Indian Ocean.
