It's crazy that a 60 ton metal airplane can just fly

Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

Its all in those powerful engines
Not really. The thrust those engines produce is only about 1/3 the weight of the aircraft. It's in part thanks to the engines for sure though.
You make it sound like 1/3 is a small number. That's enough to accelerate the plane quickly and the speed is what generates lift.
I just meant that thrust is only 1/3rd the equation. The rest is the wings that convert thrust into lift at 3 to 1 ratio. And then there is all the systems that keep it controllable and safe etc.... it's a miracle machine really....
A few jobs back I was working was on a little learjet that had a .75 thirst to weight ratio. Now that was a fun jet. Now I have 54k lbs if thrust in a plane that weighs anywhere from 100-160k lbs.
