Engineering is meant to be entertaining. This note is about the test of the robot climbing 1000 feet on a test ribbon (the idea being that a final version could climb a successor ribbon into orbit.) Note the humor in the markings being used on the ribbon to warn off pilots...

A Hidden Sense of Humor: "

I’ve been editing the video from the 1,000-foot robot test. Since I’ve been busy lately with grant writing etc., I wasn’t involved in activities like making the ribbon. So it wasn’t until I was watching the video that I noticed the sentence written in block letters on the 2-inch wide ribbon (which alternates color in 50-foot strips of bright yellow and fluorescent orange) near the top:

ATTENTION PILOT: IF YOU CAN READ THIS, YOU’RE TOTALLY SCREWED.

Our sense of humor (or at least Nyein’s) may not (or it may) be visible from far away, but it’s there.
