If it was lowered by a rocket engine then why is there dusts on the ground within ft of the capsule?

Being lowered by a rocket does not explain how they decrease speed when they approached the moon.
Don't mix the capsule with the prob of approaching the moon at least 3500 mph and not smearing all over it .
Even if they went into a so called orbit at that speed then that creates an even bigger prob for a landing.
How the fudge do you do controlled Burst with a rocket?
Do do you shut it off? How do you reignited?
Going from earth they climb against earth's gravity until the moon's gravity takes over and start falling toward the moon. They then do a burn of the service module to place them in a lunar orbit. Land on the moon as explained above. Then take off, dock with the command module, do another burn to get out of lunar orbit, fall toward earth gaining speed. Then enter earth's atmosphere that slows them due to drag. And finally parachute in.


Yes, you can control a rocket's thrust and direction. We're not talking fireworks rockets here. Without getting into much detail, you control the amount of fuel going in using a throttle.


The basic math has been known since Newton's time.

I can't see using jets to slow or guide them to there objective because the slightest variance would have thrown them off course to who knows where and they didn't exactly have gps.

Yes I admit I'm a moon landing doubter but I have a hard time believing they did this before the color TV was introduced.
Not mind boggling at all. Watch some videos on how orbits work. You seem to be thinking of it like landing a bullet on a ball but you're forgetting gravity does most of the work.

I have 101 problems with the moon landing, I only believe it because you just cant keep a secret, after all these decades someone would have talked.

How were things before they did it?

First color television sets were sold 50 years ago

First color television sets were sold 50 years ago
Wednesday, December 31, 2003
By Richard Powelson, Scripps Howard News Service

Color television is celebrating some 50th anniversary milestones, but many Americans did not enjoy it until the late 1960s or so, when set prices dropped and consumers heard their favorite shows were suddenly in color.

***************

I see you also believe that color TVs didn't exist before 1970. Article from 2003.

So, these strange craft whizzing about our skies are not ours then? Ahh... a believer in ALIENS, cannot have that on this forum !

If you believe they are ours, then there must have been some secrets which were successfully kept for many many years. If you believe they are ours, then you must also believe in a secret space program where we have already gone to other major stars with this technology. We do have the technology to make our lives far far better but it is STILL kept secret.

You can see moon dust start to kick up at ~27 secs in this video - https://youtu.be/xLu0Ak9Blog?t=27

It increases the closer the LEM gets to the moon.

It's no coincidence that these UFO sighting began when the government began testing advanced aerospace technology. They encouraged UFO speculation and undoubtedly still do today.

The plane capable of the highest speeds and highest sustained altitudes known to the world, the SR-71, is a design that started in the late 50's. It first flew in the mid 60's. Either they have kept their secrets very well or or have not been able to exceed the performance of a plane that first flew more than 50 years ago.
