The Ziroli DC-3 crash... everyone does those!
Several factors....
Inexperienced pilot... evident on the taxi out, with no elevator to assist the tail wheel authority.
After takeoff.. speed too slow.
Gyrations.. aileron induced tip stalls.. the plane goes opposite the control input, as the downgoing aileron stalls the outer wing on that side. The corrections are then extreme, and merely exacerbate the situation.
A slightly forward c.g, and more speed before taking off, and a lot less aileron authority would be nifty.
