If she was rotating (either direction), and had not enough D/S to keep from occasionally "falling" tail first, the tail would have dug in with its APU first, shed the VS, and then lost engines as the forward fuselage "flipped" over the top, the cockpit describing a large arc over the Wing center box to plant behind the engines. This means a heading at impact of ENE, and accounts for the position of all the parts, odd though it may sound....To be correct, this would need BEA's aspect at impact. it also requires more than a little horizontal and less vertical.
