OTL: The UK Government starts building the airport in 1944, pleading (allegedly falsely) military necessity as a way to avoid a long public enquiry. The Heathrow farmers are summarily evicted in late 1944, and many are not compensated until the 1950's. The Heathrow farmers celebrate VE Day scattered in exile over southeast England.
ATL: Someone blows the whistle and spills the beans, not liking the idea of seeing all that construction vehicle fuel (which had been imported at risk past the U-boats) wasted on a big project of no use to WWII, and thinks that the Heathrow farms are best left alone to help the war effort by growing food. There is a big public rumpus and questions asked in Parliament, and the airport project is shelved until after the war and after a full proper public enquiry. The Heathrow farmers celebrate VE Day on a field by the Cain's Lane junction in Heathrow village, with their farms and orchards still intact. Someone lends them an Arab stallion: they mate it to some of their cob cart mares, producing foals of good hunter type: these they send to the Army, and one of them (when adult), used as a dispatch rider horse, carries a vital message 25 or so miles fast over country too rough for a motorcycle.
