(12) Section of aft fuselage crown structure. (Targets 255 and 267: see App C Volume 2 p 7 and p 9.)
The structure fractured at body stations 1960 and 2200 and at stringers 5R and 8L. It showed evidence of heavy smoke deposits on the inner surface and heat discolouration of the paint on both the inner and outer surfaces. Deformation of the structure through impact showed a twist due to a high torsional load in a clockwise direction. This deformation is consistent with the mode in which Target 256 fractured at body station 1740.
(13) Dorsal fin with piece of empennage structure. (Target 38: see App C Volume 2 p 10.) The structure separated at body stations 2200 and 2300 and at strangers 5R and 4L. Paint discolouration, smoke deposits and paint peeling were evident on the inner surfaces at the forward and
