Lightbulb HS issue

re #1742 (permalink)

IMO applying a bit of Ocams razor - a ** possible** probable ** simple version goers like this all in a few fractions of a second or a few seconds

a) Jackscrew/fitting/pin/ breaks ( why unknown )
b) Both HS flip nearly 90 degrees to airflow such that tension on top of airplane and compression on bottom - Plane pitches up.
c) Left? HS breaks off - plane starts to roll/yaw
d) combination stress at frame forward of PB on top rips top in tension, and buckles bottom in compression. This due to tension load and internal pressure load.
e) Right HS and VS combined pull ** foward ** of PB section off-
f) align themselves with relative wind- sort of a v wing along with HS box and most-all of jackscrew - and " fly" away

OK- IF My version is partially correct- expect to find RH HS - HS Box and Jack screw and pivots and maybe part of VS pretty much together.

Enough speculation - agree that more info needed- and especially the jackscrew system and RH HS.

Have a good evening
