REQ: Info on Tempest GR7

Hi All,

I am reading a book written by John Nichol, name of the book is
"Exclusion Zone". They fly aircraft called Tempest GR7.

I have now been googling around for a while, but simply did not find any
data on what sort of aircraft this "Tempest GR7" is. Does it even exist?
Could the novelist be referring to Harrier GR7? Probably not, since in
the book it has two engines. How about Tornado GR1? It has two engines
and some of them had calls like "Tempest" during war around Persian Gulf
in the beginning of 90's.

This is driving me crazy, I usually can recognise most planes and now I
hate reading a book where they fly all the time in a plane that I don't
even know what it looks like!

I would be happy if someone could point me to correct source of
information or just tell me that the whole Tempest GR7 is bollox.


Regards,

Janne
