There are a couple of explanations for crashed vehicles, I'll ignore any videos here: - could be Von Neumann-style probes that don't care about collisions - could be willingly "crashed" to speed development up - could have been attacked by other species to prevent intervention - could be inexperienced (e.g. young) pilots I'd 100% assume that any kind of FTL vehicle also has some kind of cloaking functionality, so I wouldn't trust any photos or videos without a lot of further evidence. Just wanted to mention possible reasons - it's not 0% possible, more like 0.000[some more zeros]001%.
