YOSEMITE NATIONAL PARK, CA - Searchers on Wednesday will begin looking for a small plane that may have crashed somewhere in Yosemite National Park.

Authorities say the single engine plane disappeared from radar Monday night over the park.

They know only the pilot was on board and that the plane had taken off fromSanta Barbara for Mammoth.

Snow hampered any aerial search for the aircraft on Tuesday.

No one reported seeing or hearing the plane go down.
