As a OR nurse we use these "systems" for many cases. This super clean HEPA filtered air comes down from the ceiling, directly over the patient. This is the cleanest air and we want that clean air to then move around the patient and then flow out of the room, sometimes by vents that are at floor level. If you want the air to flow upwards, that air will bring any contaminates that were on the floor up and over on to the patient. Same on a plane, bringing up that air brings all the floor stuff with it. And Level 4 bio-labs also work the same way. Ceiling to floor, then that air is frequently incinerated also to kill the virus and bugs in it. And in a Level 4 lab everyone is also wearing isolation suits and they do not share air either. And it is frequently incinerated also.
AF-1 flys to LKangley AFB in Hampton-Newport News Virginia. Now it flys to Virgnia to perform and practice full power and very steep climbs. It frequently flys over the James River. And you know what, when AF-1 flys over a boat with 100 touristson board it shuts them all up like nothing else. It is the MOST RECOGNIZABLE paint scheme/color. You can see the seal on the door. And it is IMPRESSIVE when it looks like it is 200 feet from you. That color scheme is a symbol of the United States of America. It is INSTANTLY recognizable all over the world. I vote keep it as it is. It is a proud symbol of America. And I have never seen a bunch of tourists shut up like that when it flys over them at full power and what looks like a 65% climb. It is a sight I will never forget. And it is the blue that sets it apart.
It is not that automation is bad, but the programmers are not doing a good job. Now with the advent of AI a plane could be flown without a crew. But the AI needs to be heuristic and learn all the time. And the AI needs to share those lessons with others so they can also learn. With the sky increasingly seeing more and more flights, which will continue to swell over time. An AI is the only thing out there that can keep planes separated safely taking into consideration local weather and other data. A human can not keep all that data separate. With the advent of new supersonic and possibly hypersonic planes, humans can not think and react fast enough to keep up. Only a AI can do this. With a plane flying Mach 9 can you as a human make the correct decision in time? But right now, the programmers/engineers really need to work much harder at making sure their software actually works. And Boeing failed.
Having watched AF 1 perform full power ultra steep climbs in Virginia over the James River I do not see those plans being all able to protect. They look like they perform an almost verticle climb. Well maybe 60 degree climb. Something only a Dreamliner can do these days.
