The NTSB is in Wellington, trying to find out what caused a small experimental plane to crash into a lake on Monday afternoon. 

The pilot was the only person on board and he was found dead in the cockpit. 

Although the victim's name has not yet been released, friends say he was an experienced pilot who lived in the AeroClub community. 

Witnesses say the plane was moving wildly through the air before it came down.
