What are the sparks seen beneath the space shuttle's main engines just before launch? These sparks come from the hydrogen burnoff system that makes sure there is no excess hydrogen near the engines before ignition.
The sparks from the igniters can be seen in the video below at 1:09.

This is the second video in my 10-video series on coding a program in MATLAB to compute, display, and save a NACA 4-digit airfoil.
IN THIS VIDEO:
We clean up the GUI layout after opening the .fig file in GUIDE. We make the widths of the components the same, as well as align boxes and buttons horizontally and vertically.
