Vehicle safety applies even if you're dealing with a motley flight crew.

Motley Crue drummer Tommy Lee was in a helicopter Sunday that was forced to land at Van Nuys Airport Sunday morning (Feb. 1) after it flew too close to a Los Angeles Police Department chopper, reports TMZ.com.

Pilot David Martz was observed flying erratically when he flew beneath an LAPD helicopter that was observing a structural fire. When he was ordered to land, he touched down at Van Nuys Airport, but he and Lee were missing by the time police arrived.

About 10 minutes later, Martz was found at a nearby hotel, drinking vodka as a "celebration drink" after landing the chopper. Lee was also found, but since was just a passenger, he was free to go.

Martz was pulled into the Van Nuys police department for a blood alcohol test, which proved "inconclusive," although Martz claimed that he had only blown a .01 and .02 on two separate tests. He was not charged, but the Federal Aviation Administration plans to investigate.

Martz was reportedly charged with reckless operation of an aircraft in 2006 after he landed his helicopter in a residential neighborhood in the Hollywood Hills. He had been picking up Lee and two other passengers to fly them to a Nine Inch Nails concert.

Lee, 46, was last seen on the Planet Green eco reality show "Battleground Earth: Ludacris vs. Tommy Lee."
