Nokia!? How retro!On a recent visit to the Museum of Military History in Orlando, I saw a rather large crank handled radio beacon. Designed to be hand operated and send out a rescue signal. I suspect superseded by a nokia these days!
Joking apart, it's a constant battle to enforce the 'no-phones' carried unless turned off and in a Faraday bag with the youngsters in the military these days.
Some USAF units have the right idea of nailing (quite literally) ANY mobile phone found on the person of ANYONE in a secure area to an appropriate wall in the relevant access control point as a warning about cyber security and comsec!
