****ATTENTION TO ALL FLAT EARTHERS:****

**!!**

## 1. Are Sextants used by mariners to successfully navigate using the relationship between the Earth's Surface and Celestial Objects ?

**YES !**

## 2. Are Sextants used to obtain Elevation Angles from your position to Celestial Objects ?

**YES !**

## 3. Can you obtain an Elevation Angle from a Curved Adjacent (Curved Baseline) – SPHERICAL Surface ?

**NOPE !**

The End.

It’s ALL OVER BallTAAAAAAAARDS !!!
