How the Granddaddy of US Recon Planes Is Helping Search for Flight 370
The mysterious disappearance of Malaysia Airlines Flight 370 off the coast of Vietnam has prompted a massive multinational maritime search for hints of the plane's fate. Among the growing armada of surface and aerial search vessels is the US Navy's venerable P-3C Orion, a long-range surveillance platform still just as effective today as it was in the early Cold War.

So now you've hardwired the transponder. What happens in a real electrical emergency and you can't cut the power to the unit off? Maybe it needs a code transmitted thru a data line to disable....
Independant electrical system that runs on battery when breakers are pulled. Reduce power drain by transmitting less frequently.
Buiod a system that must respond when interrogated with a special code IF both conventional transponders are shut down.

This doesn't provide a means to quickly shut it off in an electrical emergency. If on fire or over-heating it may be inoperative and unable to accept the 'special code'. Additionally, if someone wanted, they could still find a way to get the code to turn it off in the case of a hijacking.
Not to mention the additional cost and weight of adding this kind of system and having it FAA certified.

I'm no aviator but I've been thinking a lot (kinda dangerous for a 72 yr old). Make black box batteries so they last longer. Also there should be enough room somewhere in the tail or fuselage to install a long wire antenna 5 miles long (like the doomsday 747) that would deploy automatically in the event of a water landing or crash. It would send the emergency beacon signal out further and keep the search area down to five miles or so.
Yeah baby. The P3 remains a workhorse.
So that would make the U-2 Dragon Lady the Great Granddaddy of US recon planes?
