Perhaps the crew who were operating at the time should have been aware that something was possibly amiss after the arrival and had a better look after shutdown. Not speaking up out of fear or ridicule risks all the lives of everyone who operates and rides in that machine afterwards, until it's detected. No wants to scrape a pod, it was a genuine mistake and should be owned up to. I believe that the 'just cause' accountability protects you and when it all boils down, apart from the mishap, it's just good airmanship and integrity to own up. Keg said in another thread that we should all be looking after each other, regardless, this is just another example.
