Unfortunately continuing to burn money with no hope of recovery is not a popular strategy among judges and creditor's lawyers. Customers will either get refunds or join the back of the creditor line.
They wouldn't have to set anything. The transponder on almost any modern plane defaults to automatically on, either immediately or at takeoff. With Mode C (reporting altitude) or S (& reporting more) and squawking 1200 (VFR).
These have been standard equipment (that you buy, or the school loans out) in middle-class US high school math since the 90's (and gone basically unchanged since then). The math books even have content tailored to particular models so that you'll have to buy them instead of alternatives from other vendors.
What you are likely thinking of is the "selective availability" system, which intentionally provided slightly inaccurate data to civilian clients, while military receivers could decrypt the most accurate info. But this has not been used for many years now.
Other than that, GPS is a one-way system, it does not know you exist, how fast your receiver is moving or "give" different information to one client vs another.
Even if it did, this is essentially a toy and moving slower and lower than a general aviation plane.
It uses accelerometers and other sensors because they can be sampled and integrated hundreds of times a second. The $5 gps module is 9600 baud serial and provides one update/second (or maybe 5/sec depending on which part number you pick).
This is not even close to the worst ideas Apple ever had, even if you're only talking about mice.
The original USB mouse (for the first iMac) was round, so you couldn't orient it in your hand without looking at it constantly.
And it came with a very short cord (because there was a port on the right side of the keyboard to plug it into). But then the laptops got updated with USB ports and they were only on the LEFT side of the case.
For at least a year or two you could not buy an Apple mouse for your Apple PowerBook and use it in your right hand, because the cord was too short to go around the case.
Eventually they shipped a "Pro" mouse with revolutionary elongated shape and longer cord. (...and optical tracking, and what looked like zero buttons, which were pretty neat)
If you don't go often enough you definitely won't make the same progress per session. You'll spend most of each session trying to remaster what you lost from the last one.
For powered flying, one a week is already on the low end... most instructors would recommend 2-3x/week.
Flying skills are very perishable, especially when first learning. This is why there are several different rules about recency of experience before you can do things like carry passengers, recurrent training requirements, etc.
Testing on the ground and problems with what most people would call the payload (Apollo 1 & 13), sure.
But we're comparing to SpaceX launches. Plenty of Raptor engines have blown up on the ground too.
There were 13 Saturn V's launched and all of them basically performed their mission (Apollo 6 being a bit of an exception) with 0 rapid unplanned disassemblies...
Personally I'd rather buy one from IKEA and use the change left over from $12k to buy.. a used truck to drive the sofa home in.. but apparently there's a market.
You can certainly go much higher for smaller companies producing actual custom stuff, using exotic materials, for a giant sectional instead of a single sofa, etc.
You are NOT at all (legally) free to arbitrarily turn off your ADSB on an aircraft equipped with it. 91.225(f) [1].
> Except as prohibited in [unmanned aircraft section], each person operating an aircraft equipped with ADS-B Out must operate this equipment in the transmit mode at all times unless [authorized by FAA or ATC].
A common way to add ADSB to an aircraft not originally equipped is replacing one of the lights with a uAvionics skyBeacon[2], which has a LED light + ADSB-out transmitter. So the nav light switch would control it, but you'd also now be required to have them on at all times.
JSX operates based on a loophole in the part 135 rules, but that only allows 30 seats. A CRJ doesn't have the range for (nonstop) transatlantic, bigger planes would be impractical, and smaller ones with the range won't hold 30 people.
TLS did "exist" (well, as SSL), but this was a time when you'd maybe see it used on a few websites that had it on just the specific pages that took a credit card.
It was well before most other protocols were worrying about the security or privacy of being intercepted at all. Decades before TLS by-default-because-why-not started becoming a thing (largely because of LetsEncrypt). Especially for an app that was mostly for pirating stuff. Your email and it's login/passwords, IRC, instant messaging, regular browsing, etc all happened in plain text.
And despite the physical networks being super vulnerable back then. Ethernet was mostly connected by hubs/ring/shared coax, so every device received every other's packets. WiFi was just coming around and is a shared medium. Several rounds of inept security schemes failed to even keep people who don't know the network password from intercepting nearby traffic. Most networks didn't have security on yet anyway.
It's really sort of the opposite. You don't see 727s or MD-80s at the terminal anymore (freight somewhat excepted). Airliners are used constantly, wear out and get replaced/sent to other countries. Buying another computer is a negligible cost in a new 787 or retrofit into anything an airline currently flies.
But there are tons of flying general aviation planes that are from the 50s/60's, and a long tail going back even further than that. Some of them don't even have a radio to talk on. Or an electrical system to run it.
Mandating ADSB took many years, and still has exceptions carved out. And that's a fairly simple technology. There are companies that build it all into a replacement tail light LED "bulb" to provide compliance for ~$2000.
Still that might be 5-10% of the value of your 1977 Cessna 152. If you take the cheap airframes out of the sky, that makes new pilots getting their 1500 hours more expensive before they can go get a job on the big boy planes.
