Surveyor 4 suddenly went silent at retro-ignition time, and was never

Landed spacecraft, including all of the successfully landed Surveyors,
and the fresh craters formed by many artificial impacts show up pretty
clearly in LRO imagery (lroc.sese.asu.edu/featured_sites). I would
think that had Surveyor 4 soft-landed, it would have been seen by now.
Impact of the intact spacecraft would be harder, though Lunar Orbiter
2's impact site may have been identified
(www.space.com/12476-weird-moon-impact-crater-nasa-spacecraft-crash-site.html).
