Smoke rises from wildfire, Utah (file photo)
SALT LAKE CITY -- Federal investigators are in Utah to look into the crash of an air tanker that was helping to battle a wildfire.
Sunday's crash of a Lockheed P2V killed two pilots. That, along with a crash-landing by an identical plane in Nevada, is prompting calls for the federal government to speed up efforts to modernize the nation's aging firefighting aircraft fleet.
The National Transportation Safety Board has been interviewing witnesses to the Utah crash, but investigators have yet to visit the crash site, which is expected to happen Tuesday.
Van McKenny says authorities will be looking into all potential causes of the crash, including weather, mechanical failure and pilot error.
