The Space Shuttle Orbiter frequently landed far from its launch site. The orbiter could not fly on its own, so NASA developed the Shuttle Carrier Aircraft to bring it back to the launch site at Kennedy Space Center.

The Shuttle Carrier Aircraft is a heavily modified Boeing 747 that had mounts on its back to support the orbiter. Little did NASA know, they had just developed the world’s most expensive piggyback ride!

Imagine that you're an airline pilot flying a standard red-eye route. You've done this route dozens of times before with very little variation, and this time looks to be no different. All of a sudden the primary flight display shows a flashing red alert and an automated voice saying "PULL UP, PULL UP, PULL UP" fills the cockpit.

From experience you know that there are no obstacles on this route, but your training kicks in and you execute a high-performance climb. After a few seconds, you realize that something doesn't feel quite right; the alarm is still blaring, but at 35,000 feet and climbing, there couldn't be any terrain anywhere near the airplane.

Then you notice that the GPS shows you in a place hundreds of miles from the planned route. ATC then calls you asking why you busted your assigned altitude.

GPS spoofing is when a malicious actor sends a false GPS signal to a receiver leading to incorrect GPS locations and a failure of many systems in a modern aircraft. Ever since early 2024 we've seen an alarming increase in GPS spoofing. Can we do anything about GPS spoofing, or does this signal the end of GPS?

Most of the information in the episode came from the "GPS Spoofing Final Report" from the GPS Spoofing Workgroup. Take a look at the full report for a very interesting, in-depth investigation on GPS spoofing:

Once you get your pilots' license, it's easy to view flying as a chore, something that you must do every month to stay current. The real joy of flying comes from the adventures that having a pilots' license opens up to you.

This week, I am joined by my Kiara to discuss some of the adventures that we have done together in the airplane, and the ones we want to do in the future!
