Let me tell you, there is quite a lot of aerodynamic bufferitng, not to mention trim changes. My gut told me it was hard on an aircraft. Disturbed airflow from beneath the elevator.
.... The pullup at the at the point of jettison, whether commanded or commanded would have put a lot of stress on that spar, in this accident. The result is there for all to see.
These comments from Richard Jones are very interesting, especially his gut telling him that the drop was hard on the aircraft.
Is there something going on that we have not factored in to load dumping?
I wonder if the high density of the water flowing from the hopper under the wing would increase the forces applied around the wing root
attachment structure and strut attachments as a consequence just from the high density water flow and/or buffeting around the wing and tailplane in itself?
