From Wikipedia >In fact, theory predicts – and experiments confirm – that the air traverses the top surface of a body experiencing lift in a shorter time than it traverses the bottom surface; the explanation based on equal transit time is false. So the effect is greater than equal time transit. I've seen the GPT5 explanation in GCSE level textbooks but I thought it was supposed to be PhD level;)
