I remember a 104 and a Phantom trying to get on each others tail at altitude for several minutes near Laarbruch in the 80's. Neither had a terrific turning performance and the Phantom eventually broke off and made a run for it.
I also remember one of our Jags diverting to Baden–Soellingen after a wire strike. We had to change the No.1 engine and the 104 guys were amazed when I declined the offer of chains for the ground run. They didn't realise how little thrust the Adour had compared to the J79.
