fuel tank supposition?
2 holes, minimum.
still image in flight shows fuel venting not from the jettison system
video of approach, touchdown and landing rollout from inside and abaft wing (shows the partial spoiler deployment post touch down...) has venting fluid over the inner area of the flaps, that is not characteristic of atmospheric moisture (continues after touchdown...)
2 holes or more exit, therefore entry, #2 Tank. Question is if it went in via the lower skin or the spar. Spar = expensive. (skins alone are not going ot be cheap)
FDR
PS crew did a nice job.
