I haven't heard the "resurrect TSR2" idea yet.
There were some wonderful old designs that could be re-engineered, but don't you think we could do better today? Or have design, materials engineering and aerodynamics stood still for the past 40 years?
Anyway, we'll have fully operational F-35s in a couple of weeks so we won't need anything else.
EDIT: Malcrf, just seen your post. Yes, the UK could find a cheaper alternative (as you say) and, yes, Typhoon has a long way to go.
