"there was Simply NOT ENOUGH HORSEPOWER to "blast them OFF" of the moon's surface, again Orbit & "Sling-shot" back to EARTH."
Rocket engines are not rated by “horsepower.” It can be calculated, but you will not see that term in a specification for a rocket engine.
The ascent stage at liftoff weighed about 10,000 pounds on Earth, but in 1/6th lunar gravity it was less than 1,700 lbs but produced 3,500lbs of thrust. Since the gravity on the moon is only 1/6th of what it is on Earth and there is no atmosphere to slow the LM down, it takes less thrust to lift the mass off the surface.The ascent engine used a 50/50 mix of hydrazine and dimethylhydrazine (the mix was called Aerozine 50) with dinitrogen tetroxide as an oxidiser. It is a self-igniting (hypergolic) mix that provides a lot of thrust and a colourless (invisible) flame. The fuel and oxidiser was pressure-fed into the Ascent Propulsion System, which gave it the necessary 16 kN thrust and 311 seconds specific impulse needed to reach lunar orbit. After the LM returned from the surface, it entered a highly elliptical orbit at slightly less than 10 nautical miles and just over 5,500 FPS. This orbit would have carried it out to 48 nautical miles, but was adjusted by RCS thrust a few minutes later to roughly 62 x 44 nm at about 5,400 FPS. The LM then gained on the CSM, not just because it was going a little faster, but because it was climbing from a lower orbit, and lower orbits have shorter periods.
A little over three hours after liftoff, the LM’s orbit intersected the CSM’s at about 60 nm, and RCS thrust brought it into a nearly identical orbit of 63 x 56 nm, closing on the CSM by about 10 fps. Finally, a series of short braking burns brought the two ships into hard dock.
The ascent stage of the LEM, having lifted off and docked with the CM, was subsequently jettisoned. It was the SPS that performed the TEI burn which lasted approximately 150 seconds, providing a posigrade velocity increase of 1,000 m/s (3,300 ft/s) sufficient to overcome the gravitational influence of the moon and send Apollo on its three day fall back to earth.

You have regurgitated and parroted a series of claims about subjects that you demonstrably have zero understanding of whatsoever that have all been refuted here and you simply disregard all the responses to you, assume your dumb default position of accusing someone legitimately challenging your falsehoods as being a 'shill' and turn tail and run to the hills in the process. To return to your original claims -
"the blueprints for the lunar module and where they are, they mysteriously disappeared"
No they didn't. The full specifications and schematics are readily available online, in academic journals, PDFs, and a wealth of available literature. Also, in engineering, blueprints evolve and are subsequently subject to revisions. Moreover, some of the original Grumman diagrams and drawings have been sold under auction by Southeby's and are owned by private collectors.
"along all the NASA mission control tapes that collected all telemetry and location data. The sacred original film of Armstrong's first step on the moon has been conveniently 'lost', as well."
Again, utter nonsense. Do you even understand what telemetry is?
Some back up recordings of raw analogue video transmitted via unified S Band during the Apollo 11 EVA was at some point erased. The tapes were made using specially designed, high-capacity recording equipment in order to capture the raw transmissions at source in case anything should go wrong with the process used to convert them to a standard broadcast signal. Once the conversion and transmission was complete, the recordings were no longer needed for their original purpose. Any magnetic recording media has a limited life. The magnetic fields of the stored data decay over time. For this reason, and because high-grade tapes were very expensive, they were never considered an archival medium anyway. The data on those tapes, including video data were relayed to the Manned Spacecraft Center during the mission. The video was recorded there and in other locations; there is no missing video footage from the Apollo 11 moonwalk. There was no video that came down slow scan that was not converted live, fed live, to Houston and fed live to the world.
During the search for these tapes, the team came across broadcast-converted tapes that were far superior in quality to anything previously seen. There were tapes recorded in Sydney, Australia, during the Apollo 11 mission. They also found kinescopes at the National Archives that had not been viewed in 36 years that were made in Houston. Sifting through the CBS archives they uncovered tapes that had been fed directly from Houston to CBS - the raw data as recorded and archived.
The relevant information from the telemetry was evaluated real-time and shortly after the missions, then the tapes were re-used. The majority of that information coming over telemetry was switch settings, voltages, tank volumes, etc., on a craft that will never be used again. Engineering data about performance of the various systems was sent back to the ground for analysis and diagnosis of any problem. Also, biomedical data on the astronauts. Today, such data would be measured by an analog-to-digital converter and transmitted digitally. At the time of the Apollo program, computers were heavy and expensive. Analog data was encoded in semi-analog formats—frequency modulation, phase modulation, pulse-code modulation—combined into a microwave signal, received on the ground, decoded with special equipment and recorded on large reels of magnetic tape. For viewing the data, the signals were often written out onto long charts with strip chart recorders. Data on magnetic tape that needed to be kept, such as telemetry data, was always printed out as a hard copy. So after each Apollo mission a comprehensive mission report was published where all the extracted telemetry data was analysed and presented as charts and graphs and tables. The telemetry for all the Apollo missions would be hours and days of details of obsolete equipment working normally. Nobody cares about that and the people who might know how to make sense of it are passing from the scene, as is the machinery that could read those tapes. Nowadays, vast quantities of data can be recorded to disk for negligible cost. In the late 1960s and early 1970s, that wasn’t the case. As explained, data was recorded on big, heavy and expensive reels of magnetic tape that could only be read on big, heavy, specialised equipment. There are real-time recordings and transcriptions of all the missions and the data/confirmation can be found in the post flight mission reports. These are available in PDf format for download.
Everything was backed up and transcribed. Every scrap of the original data from the landings is carefully archived away. This is a classic example of the inflation of events in the minds of conspiracy theorists that you parrot. Several backup tapes from one mission EVA gets recorded over. But that's exaggerated to the fallacious claim that involving all footage and all telemetry from all six landings being destroyed.

"We could go there now, but we never had the technology back then to make it there."
Specifically, what technology was lacking?
"Just look at the lunar module...what POS that looks like it was made by a group of drunk collage students."
An entire branch of specialist expertise called aerospace engineering already have. For over half a century. All of the specifications and schematics are readily available so there is nothing stopping you doing so either. How is it, that a random, insignificant underachieving troll and gullible believer in dumb online conspiracy theory with no knowledge of the subject whatsoever claims to know better? Go ahead then.
"You expect to believe that was made by some of the best engineers in the world?"
Grumman, and yes it was. Again, what do you know that they didn't?
"Where is all the telemetry tapes and blue prints?"
What do you mean by telemetry tapes? Do you even know what telemetry is? In engineering blueprints are original drafts that do not take into account subsequent alterations and modifications during the developmental and manufacturing process.
"OH, what.........they were all lose they say...................... Priceless."
No one has said anything of the sort. The The blueprints for the Saturn V rocket for example are stored on microfilm at Marshall Space Flight Center, and the Federal Archives in East Point, Georgia. Regarding telemetry, some magnetic back up tapes from the Apollo 11 EVA, which were never intended for archival use and are now obsolete anyway, were reused. Others from subsequent missions were sold at auction to collectors. All of the telemetry was recorded and archived, but consists of readings, switch settings, biomedical data which has no use today. You can view telemetry from all of the Apollo missions online in real time.
Mate, you haven't got the slightest idea what you are talking about. You can't even write basic English or compose a coherent sentence ffs. Why are you doing this to yourself? You are a prime example of everything that is wrong with internet access.

Fascinating. Hollywood you say?..so what about Shepperton, no wait, wasn't it Elstree...no, no, definitely Pinewood UK. Hold on, I thought it was Cannon AFB New Mexico? Or surely Area 51 Nevada? No, hang on, what about the Utah or Arizona deserts? Nope, definitely Devon Island Canada! You absolute goons can't even get your stories straight. I guess it depends upon which dumb conspiracy theorist that you allow yourselves to be duped by.
Got to say though, that must be some 'Hollywood Movie" to convincingly replicate, uncut, the 1/6th gravity and the vacuum of the lunar surface - not to mention the precise reconstruction of Theophilus in The Sea of Tranquility; the Head Crater vicinity, Ocean of Storms; the Fra Mauro Formation near Cone Crater; the eastern edge of Mare Imbrium, Hadley Rille; The Descartes Highlands; and the eastern edge of Mare Serenitati in the Taurus Littrow Valley. Shout out to the props department too, that managed to fashion fake moonrock consistent which each of those six landing sites and collectively dupe an entire branch of science called geology for over half a century in the process.

@vacuumandgaspressurecoexisting
I'm not sure if you're actually attempting to be serious here, having a joke and simply trolling, or are genuinely that ignorant.
Firstly, the supposed rock was a private gift to former prime minister Willem Drees Jr in 1969. Drees had been out of office for 11 years, but was considered an elder statesman. When Drees died in 1988, the 'rock' was donated by his family to the Rijksmuseum without verification, and having been exhibited for two decades was later discovered to to the curator's great embarrassment to have been petrified wood. It had nothing to do with NASA or the US government. You could have verified this for yourself.
Secondly, the goodwill rocks given by NASA to the Dutch government are accounted for in other Dutch museums throughout the Netherlands and encased in Lucite as were all moon rocks officially distributed around the world as gifts.
Thirdly, in 1972 BRGM in France were one of the first independent laboratories to examine a moon rock returned from the Apollo missions. Since then, and throughout the last 50 years, samples from the Apollo manned landings have been distributed throughout an entire branch of science called geology, worldwide for the purpose of petrological analysis.
For example, take a look at the work of geophysicist Jenika Greer et al. at Chicago University, using APT to analyse grains of sample 71501 from Apollo 17. Or planetary scientist Erica Jarin who specialises in the analysis of explosive volcanic deposits on the lunar surface. Her work was based upon samples returned from Apollo 15 and 17. Meanwhile, planetary scientists at The Open University in the UK are spearheading a microscope collection of over 550 rocks collected during the Apollo missions.
