I am a former RAF Second World War pilot, more than 80 years of age and not yet senile.

Why has no one tried using crop-dusting aircraft or helicopters to blanket-spray with disinfectant the areas worst affected by the terrible spread of foot-and-mouth disease?

It would be much faster, cover a bigger area and the spray descending would kill off any airborne germs.

It would be expensive but cheaper than killing off thousands of perfectly healthy animals "in case they are infected".
