KUSA- As 43 ships scoured the sea and 58 planes took to the air, day 9 of the search for Malaysian Flight 370 still yielded no possible location of where the plane might be. There is still no sign of the plane, which vanished with 239 people onboard - and some experts are now saying it is possible Flight 370 will never be found.
As the huge search area grows, there are several new developments in the investigation. One of those includes the fact that investigators are now examining a flight simulator found in the captain's home.
The sheer number of nations involved in this search is also growing by the day, with more than a dozen countries working to find Malaysian Airlines Flight 370. Despite all of those resources, though, the mystery surrounding what happened to the plane only deepens.
"It's a modern day, Amelia Earhart, lost flight," said 9News Aviation Expert Greg Feith.
The flight took off from Kuala Lumpur last Saturday, heading towards Beijing, before inexplicably changing course and heading back across the Malaysian peninsula. Someone shut off two critical communication systems on the plane. The final words heard from the cockpit came just before the plane entered Vietnamese airspace.
Based off of pings detected by a satellite, investigators believe the plane flew for seven and a half hours and headed in one of two directions: to the northwest, towards Central Asia, or to the southwest, towards the southern Indian Ocean.
Radar information, shared by several countries in Central Asia, doesn't show any evidence of the plane entering their airspace, which means search efforts are now expected to focus on the southern Indian Ocean.
In the meantime, families of those on the flight are left to wonder: what happened to their loved ones and just how long will the search go on.
"Unless we really start to see some positive results in the next probably 96 hours, I have a feeling that there's going to come a point where they are going to start to terminate the search," Feith said.
Experts believe part of the reason the search could end up being scaled back eventually is because of the sheer number of personnel and machinery involved, at a potential cost of billions of dollars a day. They say it will be very difficult to find wreckage in such a vast area of the southern Indian Ocean, where the average depth is more than 12,000 feet.
