:I've added an explanation for the title text but am unsure of the "engineering standpoint". Maybe someone with knowledge in the area can elaborate on that. Is landing inherently more difficult than launching?[[Special:Contributions/162.158.88.128|162.158.88.128]] 08:42, 19 March 2019 (UTC)

:: It makes sense from an engineering point-of-view because it tested if we can get things to the moon and that our math fits with something cheap and worthless. That cheap and worthless thing we threw at the moon? Nationalism [[Special:Contributions/162.158.90.90|162.158.90.90]] 17:02, 19 March 2019 (UTC)
 
  
 
Probably about how the engineers wanted to test what they could do before they could actually do it. (Oh,and Luna 2 impacted at 22 km/s) 20:10, 18 March 2019 (GMT)

:The actual sad part is it probably isn’t a joke. At least it’s a long and drawn out poorly constructed one. People are idiots, and flat earthers can be real. This person isn’t making fun of them.

::What are you talking about. I looked it over again, and it's 100% definitely a joke shitpost. Whether you think it's funny or not is up to you, but it is definitely intended to be a joke. I've seen a lot of conspiracists, and this ain't one of them. [[User:CCCVVVA|CCCVVVA]] ([[User talk:CCCVVVA|talk]]) 08:10, 30 March 2019 (UTC)

:That impact speed still sounds ridiculously high,  Escape velocity to break free of earth orbit is, IIRC, 11.186 km/s (roughly 40K kmph or 25K mph), and it takes a massive rocket to achieve that.  Most of a trans-lunar flight is unpowered using either momentum built up by the initial launch thrust or the gravitational pull of the moon itself.  I find it hard to believe that impact speed, even allowing for gravitation influence of the moon itself, could result in an impact at almost 2X the speed needed to get away from Earth in the first place.[[User:RAGBRAIvet|RAGBRAIvet]] ([[User talk:RAGBRAIvet|talk]]) 07:24, 19 March 2019 (UTC)

::22 km/s seems to be wrong. Wikipedia along with a few quick google searches put the impact speed at around 3 - 3.3 km/s. To me (far from an expert) that appears more realistic but still fast enough to cause significant damage. Whether things are literally vaporized at those speeds I leave for others to determine.[[Special:Contributions/162.158.94.2|162.158.94.2]] 11:31, 19 March 2019 (UTC)

:The whole point of the "bomb" was to avoid all of the little "flags" (they actually contained the coat of arms) from being vaporized.  The idea was to take a sphere, hurtling towards the moon at speed X - then to explode with an explosive speed of Y.  The flags at the 'front' of the bomb would then be propelled towards the moon at speed (X+Y) but the ones at the 'back' would be moving at (X-Y)...it was hoped that this slowing down from the explosion would result in at least some of the flags arriving intact onto the lunar surface.
 
:It's a very clever idea because it works even if the sphere is tumbling in some uncontrolled way...and it's VERY simple.

== shrapnel Trivia ==
 
 
I disagree with the statement(s) in that section, or at least with the label "incorrect" -- it's at most "using the term loosely". The link provided goes to a "shrapnel '''''shell'''''", which is ''not'' quite the same thing as the idea of "shrapnel" anything. Having "pellets [launched] at a target" is sufficient IMO, even if in this case they are flags. As that page clearly says, <blockquote>The term "shrapnel" nowadays is often used to refer to lethal fragments of the casing of shells and bombs</blockquote> Language is fluid, and words evolve to have other meanings besides their original one. -- [[Special:Contributions/172.69.54.87|172.69.54.87]] 06:28, 4 April 2019 (UTC)
