@Delta Your integration with Virgin Atlantic is not good. I paid for a Delta ticket, but check in doesn’t work, TSA precheck doesn’t work. Sky miles credit doesn’t work. Really annoying.
@veritasium@alexkusenko I just read Rick Cavallaro’s one-D analysis. It is compelling. It shows that a vehicle with inefficient components transmitting wheel rotation energy to a prop can run faster than the wind while accelerating downwind. I don’t see any errors. I’m curious to learn what you think.
@alexkusenko@veritasium@alexkusenko the exact data you asked for has been provided. The experiment clearly shows you are wrong. 2.8x over an extended period cannot be dismissed as measurement noise or inertial effects.
