http://news.bbc.co.uk/1/hi/england/norfolk/3714251.stm The rest of the article makes interesting reading. Now, i'm not a Fighter Jock or a Patriot shooter , but one or 2 bits in the article seem iffy. The first thing that comes to mind, wasn't this aircraft one of a 2 ship recovering? So you have one squawking correctly, and another contact in trail flying on the same course and possibly airspeed , and you shoot at it? Sorry I'm over-simplifying trying to get my head round this. Maybe a Tonka Mate or Rocketeer or somene in Airworks could comment?
