# Get to 13000 Feet Without Using Plane

The rising cost of skydiving tickets is due to rising fuel costs.

How can we get people to at least 1000 feet without using a plane?

- Jump off the world tallest building Burj Khalifa (List of tallest buildings - Wikipedia)
- Human cannonball, the highest height is 200 feet by David “Cannonball” Smith Sr. (As of 2023, Human cannonball - Wikipedia)

Based on Google Bard, here is the equation for human cannon ball

`h = (v^2 * sin^2(theta)) / (2 * g)`

where

- h is the maximum height
- v is the initial velocity
- theta is the angle of launch
- g is the acceleration due to gravity (9.81 m/s^2)

In theory, you can shoot a human to 13000 feet.

```
v = sqrt(2 * g * h)
h = 13000 feet * 0.3048 meters/foot = 3962.4 meters
v = sqrt(2 * 9.81 m/s^2 * 3962.4 meters) = 261.7 m/s
```

Therefore, the initial velocity needed to reach a height of 13000 feet is approximately 261.7 meters per second.

Air resistance would reduce the actual height that the projectile could reach. The amount of air resistance would depend on the shape and size of the projectile, as well as the speed at which it is traveling.

I wonder if there are other realistic methods? Star Trek’s tractor beam don’t count.
