British Airways – A320 – G-EUUG

Looking on A.net, the last photo of G-EUUG was on November 22nd 2004. I have been to LHR 5 times since then and everyday, virtually every A320 comes in….except G-EUUG. 🙁
Has anyone seen this bird since then and could tell me where it is lurking?? ( This is the only BA plane I need to mark off)
