All,
Knowing that Bletchley Park is not just around the corner for German bombers, let us just assume:
1) Bombing in August 1940
2) A few bombers get lost and somehow bomb Bletchley Park
3) Mansion and the preliminary huts burned down
4) The main people killed
Could it have happened? Maybe
The big WHAT IF :
1) Was Turing irreplaceable?
2) Who was left to take up the job?
3) Would it all have to be restarted with a new trawl of 'geniuses' ?
4) Would it have had major impacts on the war?
