The twin-engine Aero Commander plane was spotted flying in the
high desert north of Los Angeles for several hours during the
afternoon at about 18,000 feet and could not be identified or
contacted by the Federal Aviation Administration, agency spokesman
Donn Walker said.


Possible radio problems in a 150 - ok. Harder to swallow when it's an Aero
Commander.

There is no requirement to be monitoring the radio below 18,000' in
that area. Without more details, it's difficult to know how
appropriate this intercept may have been.
