I read the Wikipedia debunking conspiracy theorists points, and looked for the evidence they supplied....I'm interested in all perspectives, not just one.
But that's still not using science, that's still just accepting (or not) other peoples' word.
I actually took the time to use my own brain to calculate it all for you, rather than just post you a bunch of tired links.
That's using science.
If you'd like, I could go into
much greater detail about types of radiation and how they affect human tissue and so on and so forth. But it would be very boring.
So the ball is in your court. Why can't a rocket weighing 45 tonnes take off using 7.5million lbs of thrust take off when an aircraft of 333tonnes using only 120lbs of thrust can?
Modern rockets used on the space shuttle are even heavier (in excess of 2000 tonnes). But they can still take off.
Some more maths:
One model rocket has a mass of 50 grams and a rocket engine that produces a thrust of 5 Newtons for 1 second.
To find the weight, 50 g needs to be changed into kilograms by dividing by 1000. This gives a mass of 0.050 kg. Weight is mass (in kg) x 9.8, which gives 0.050 x 9.8 = 0.49 N.
The resultant force is the thrust – weight = 5 – 0.49 = 4.51 N (unrounded).
Acceleration = resultant force divided by mass = 4.51 ÷ 0.050 = 90 metres per second squared (90 m/s2). This means that, every second, the speed of the rocket increases by 90 m/s.
This is nine times the normal acceleration due to gravity.
