Perhaps the lead pilot knew exactly what he was doing and this is what happens when the lead wants to teach the wingman a lesson? Or he also knows the cotton picker operator and tried for 2 birds with one Stearman?
Can you imagine being in the cotton picker, which likely costs far more than those planes combined, just cruising down the row, when out of nowhere it's like a bomb explodes behind and two fast shadows go by?
Or almost as bad, you come out after the dew has dried in the mid-morning, all ready for another cotton-pickin day, do the walk-around and find a wheel and some metal just lying there and then going around a bit more and see the huge dent where the wheel hit. How long before the realization hits that the wheel arriving from the other direction would have put that wheel through the windshield and splattered you all over the remains of the cab?
