Thanks, still researching this point of the MIg. I pointed Flt Lt Comer's daughter towards the recent Aeroplane article in which he gets a mention or two, as he does in 'Listening In. However, on some forum or other, and I am gettng old(er) and cannot recall which, someone mentioned a Mig attempting to interfere. Certainly comparing dates et it seems his AFC was connected with the electronic intelligence gathering pre-Suez..
