Pardon, it's acoustic actuated rether than radio actuated on those blowout 
preventers.  The also have a record of being occasionally trigger by random 
sound waves.

The reported failure rates on all deep water blowout preventers is rather 
interesting as well.  Hydraulic and acoustic actuated have similar failure 
rates and, on cursory examination, failures seem to average between one and 
two per month.  The current problem may be a rare occurence, but the 
underlying failures are not.
