Early in the expedition I was in the Cat's Paw nebula, racking up some wonderful discoveries. I landed by Orca on a tame little world to get some screen shots of the fumaroles or somesuch. It was a low-g planet, nothing very scary.
I lifted off again to reposition my ship, flew in a big backwards loop that was woefully miscalculated--I was belly-up careening towards the ground, and I guess my "up" thrusters weren't ready for the job of slowing descent (that's not their job, eh?). So I braced for a bump. No big deal, I had my shields up.
And then I bounced off the ground and exploded. Quite astonishing.
So, I've recalibrated my expectations about what kind of impacts my shields and hull can withstand, and I'll be flying less dangerously from now on...
Side note, I also lost an SRV very recently under mysterious circumstances. I was cruising along a planet (again looking for screenshots) and came down from a shallow jump on my wheels and explode. Down from 41% hull to 0% for seemingly no reason. I guess that's why I brought two. Anyway, I've heard there will be an outfitter at the core, so I guess it's not a big deal.
