fragile parts no longer "broken by aero forces"
Extendable antennas and solar panels were formerly destroyed by 'aero forces' when moving quickly through sufficiently-dense air.
The attached save, loaded in 1.7.3 (or 1.9.1) has these fragile parts destroyed; the same save loaded in 1.10.0 has the parts survive.
Reported here https://forum.kerbalspaceprogram.com/index.php?/topic/195440-arent-solar-panels-supposed-to-snap-off-during-re-entry/
where it was suggested this is possibly related to #25744, but there mechanical damage makes the solar panel non-functional, just the graphics are wrong.
