@RetF4 and @PJ2
The SS2 has only started to open the lower part of its intended flight envelope and has not even come close to the achieved performance of SS1. Itīs a major scale-up, and clearly it needs time.
Here is footage of one of the SS1īs above 100 km flights, have a look at the rolling motions.
I appreciate that in increasingly straight-up motions the notion of bank angle vanishes, however there must be limits to roll rate both for crew and vehicle. Not sure what those would be though.
On the footage that has appeared of the accidented SS2 flight in those 9 seconds or so I have seen no indication of any significant oscillation, maybe more close-up and detailed footage will come out lateron. The NTSB has so far been quite open sharing factual information on the accident.
