You mean your graphic and his second one. Agreed. I'm talking about the differences between his first one and his second one, which are quite significant.
Consider my first graphic to be the general case on the way down and the second to depict the flight condition at impact with the difference being the angle of attack. Of course, the actual angle of attack at impact will be dependent on surface wind speed and direction, but it was clearly much more than 40 degrees for the stated rate of descent and ground speed at impact and might even have been more than 61 degrees.
