Devil's Lake didn't populate, not sure why, maybe too difficult to disambiguate? It's a city in North Dakota, but state parks in Oregon and Wisconsin.

I can remember a decade ago having to clean my car’s windshield each time I filled up at the gas station. Now-a-days in both the US and Germany I find it a rarity - my wipers can generally get the one or two splats. You’ll notice a bit more on the country roads vs interstate/autobahn but such an alarming difference overall.

I've been trying to get my organization to use ODM, but finding it difficult. The problem is analogous to the issues that Gimp has to Photoshop or Linux to Windows -- ease of use. Additionally, even if you properly configure the software the quality still is not comparable to the big proprietary players in the photogrammetry field: Bentley Systems; Pix4D; Drone Deploy.

A major reason for the quality issues is that the major drone manufacturers work directly with the proprietary photogrammetry software providers in the field to optimize the algorithms to their drones. These drone manufacturers then promote these proprietary solutions. This puts ODM at a disadvantage as there is no short-term financial incentive for manufacturers to promote ODM.

Like other fields, the proprietary photogrammetry industry is increasing moving to implementing their solutions exclusively in the cloud. This is forcing folks to give up their data and building a data moat - a problem for my organization.

I hope ODM keeps developing and becomes as ubiquitous as linux. Its quality is getting close for my organization to consider its implementation. Keep up the great work!

There are moments a pilot has seconds to react and disengage autopilot.

Example: Traffic Resolution advisories require a 5 second reaction time and 2.5 seconds for any follow-on reactions. This reaction time includes the time to disengage autopilot and also put the aircraft into a climb-or-dive. Studies show that a situationally aware pilot takes at least 2 seconds to start the reaction, and another second to achieve the proper climb/descent. There are other times on e.g. approach, or ground collision warnings with even narrower margins for disengaging autopilot.

Pilots generally know when they need to be hyper-aware with autopilot and so do competent Tesla drivers. If there are issues with the name "autopilot" for Tesla, the same argument needs to be made for aircraft manufacturers.

Apple has started to implement service workers in the latest Safari, but it still lacks behind the other browsers - I suspect they are worried it will provide a disincentive for applications to be hosted on the app store.

My biggest draw to PWAs was the ease of which I could deploy an intranet app on portable devices with spotty connectivity. This works fine with the appcache, which is what I currently use, but service workers require SSL and self-signed certificates are a no-go. This adds to the complexity of using service workers in a simple intranet hosted PWA. Also, back to Safari's poor implementation of service workers, the amount of time a PWA will reside in the browser is unspecified. I can only imagine the the headaches it will cause if the PWA drops randomly. So I'm avoiding service workers in my PWAs for now.

When appcache deprecates (it's slated to), maybe it will be time for me to go native if I am going to have to add complexity regardless.

> the result will be having to live with regulation and oversight like every other industry.

The only other industry I think could be comparable to this, from a privacy standpoint, would be the banking industry. They are largely flying under the radar during all of this, any hypothesis why? Is it because their regulation and oversight is working like you are alluding to? Or is it because the banking industry has not been caught...yet?

A consideration not listed on the OP is that Air Force pilots are required to conduct partial-flap landings on a continuing basis to maintain qualification. This could explain why the flaps do not appear to be in landing configuration. Normally, this training is conducted in the simulator, but if the president is not onboard and and the aircraft is inbound for maintenance at Boeing Field this would be plausible.

Partial flap landing distance is dependent on the aircraft, but 4,000+ feet as the position suggests would be very reasonable. The pilot could have also intentionally landed long to expedite taxi to parking.

All that said I still have no idea if the aircraft is arriving or departing.

More on application: Historically, KFs are used extensively for sensor fusion in the aviation industry. Aircraft (and missiles) use internal gyroscopes(INUs) for navigation in association with GPS. The INUs are prone to drifting and corrected with Kalman Filter estimated real time drift errors. These error rates are computed while GPS information is available and continue to be corrected in the case of GPS loss.
