I heard an amusing story once (I don't know if it's in that book) from a Saffir who flew Constellations into Biafra (from Sao Tome?). All their work was at night with no lights. The Nigerians had MiGs that would do patrols to look for them, no particular night-fighting capabilities just 'see if you can see something'. One of their Saffir mates (Charlie Somebody) got a job flying those MiGs. Through a 'common contact' they managed to agree a mutual VHF frequency. Charlie would always do his patrols with his nav lights on. If they saw a set of nav lights in the sky, the Saffir Connie pilots would quickly dial up this frequency and transmit "
off Charlie" and would watch the nav lights turn away...!!
