Shame the Sidewinder is an INFRARED AIR TO AIR missile, the Tornado ECM kit will not automatically lock onto a hand-held radar as the PFM would be recognised as a non-threat and also the aircraft would not likely to be flying live armed and even if it were there would not be an automatic launch capability enabled in peace time on a training exercise. The defence against radar threats is chaff not an air defence missile! Or at least it was on the Harrier up to last year.
So this sounds absolute bo**ox to me.
