This is the same fallacy about being in a runaway lift(elevator) where the occupants are asked to jump upwards just before impact with the bottom to save thenselves! Won't work.

the downwind turn myth Is for stupid people to believe in. Turning into a headwind does not translate into an increase in airspeed derived in any way from the headwind. For exactly the same reason, when I turn in the aisle and face the other direction, thus instantly changing my groundspeed to a negative, I feel no change in momentum.
