Re: Well, let's be accurate here
"I sincerely hope the engineers responsible were at least thanked."
Before the landing of Spirit and Opportunity, JPL director Charles Elachi said if this landing works I'll give you guys whatever you want. Someone jokingly said, "free ice cream." After the landings, JPL management set up ice cream coolers in the hallways of rover operations, and for the first few months while we were all living on Mars time, they kept the coolers stocked with ice cream bars. So yes, that was a proper thanks.
