Loving this thread. Takes me back many, many years to when I used to man co.freq. 131.8 (Bealine London)for the then BEA flight ops. This was operated by both a button on the mike and, for hands free, a floor switch. How many times was I caught out by someone asking me some very personal question about my sex life and wondering why they were giggling, till I saw the red TX light on the set glowing and shoved their foot off the floor switch !!!!!
