Flare?
THIS IS NOT BEING JUDGEMENTAL - purely observational.
If you play the approach over and over the path to runway is constant - NOT body angle which does alter but FPA/trajectory....watch the path of the wheel on the failed gear - the ROD does not appear to alter towards touchdown....so possible firm landing on single gear.
I know the DASH gear has a bit of history and always looks a bit gangly and fragile to me....plus with the Dash got to watch the tail clearance......
I feel for anyone flying today...tough day in the office....but good that all got out ok.
Again - this is OBSERVATIONAL not critical.
