You are correct. GATCO assisted a military member known as 'spot' (IIRC!). It was in connection with a fatal CFIT incident involving 2 USAF F-15's (again, if the grey matter serves me correctly).
There was a huge thread on here at the time. GATCO provided support to the individual and I believe this was hugely appreciated.
Edit:- found one of the threads
