French could be using one for Trials work, I've seen two types flying post operational out of service dates by a couple of years (for example The last Lightning I every saw flying was in mid 1991 (out of service in 1988 and being used as radar trials aircraft by BAe) and Tornado F3 (saw flying twice in 2012 or 13, out of service in 2010. Being used on Meteor AAM Trials). More likely an Alpha Jet or Mirage F1 though (The French were helping Liyba reactivate their F1 fleet).
