I thought 121.5 was still monitored
It is at the moment over the UK. The weekend flyers usually get quick a response from the fine folks in Distress and Diversion (D&D) to their practise "Pan"/real "Pan" calls on 121.5, and commercial traffic with the luxury of multiple radios will have usually have one set up on 121.5 (as mentioned in report).....oh, and various USAF european bases still insist on running a "dawn chorus" check on the frequency.
However whether the equipment used is still fit for military purpose in the 21st century is one for the experts.
