Bristol aircfat company that is.
We will asume full cooperation with between the company, Air Ministry, RAF and/or FAA. Blenheim starts off as it is historically, next opportunity might be torpedo bomber, 'classic' and/or dive bomber, day and/or night fighter, fighter-bomber etc. Preferably using Bristol own radials, but nothing firmly tailored for them. Aim is to out-perform and out-do OTL Bristol A/C, the company being encouraged to use latest known aerodynamic data for that goal.
'ww2+' meaning that resulting aircraft are usable well after ww2.
