>Buses are at alt==0 and never over an ocean And what does that have to do with it? In the event of a passenger jet crashing into the ocean an enhanced transponder system would not raise passenger survival by any notable rate (because aircraft crashes where the passengers survive and aren't immediately rescued are incredibly rare in the modern age). Aircraft hijacking where the craft and passengers go missing is incredibly rare even among hijacking incidents.
