Yes, if the missile is coming from the same aircraft that is guiding it, it will follow a similar path to the line the laser (and camera) is looking. The missile can still be going near the speed of sound and appear motionless in the camera because all of its speed is directly away from the POV of the camera

The oxygen requirements only come into play when you fly depressurized. The reason that passengers aren’t on oxygen when you are flying pressurized at 30,000 feet (probably 5-7,000 ft pressure altitude inside the plane) is that the air they are pressurizing (thin, high altitude air) is still the same ratio of nitrogen/oxygen/CO2 even though there are smaller amounts of each.

The FAAs requirement of people being on supplemental oxygen only matters in non-pressurized flight, like small Cessnas and pressurized aircraft experience a depressurization emergency.

Makes sense to me, the last time I did a long bike ride was over a decade ago. With my lack of cardio even a handful of miles sounds daunting.

That’s a completely valid point, with less cars there would be a lot more space with the lesser need of parking lots

This graphic does not need pedestrians or bikes. They aren’t competitive with vehicles of any kind when you start talking about multimile distances.

A more realistic simulation would be including the loading time for each vehicle type (car/bus/train) for a 5, 10, and 20 mile distance. That way you see how these vehicles are actually used rather than a shitty first past the post “race”. Removing the loading/unloading times of each vehicle wildly skews it in mass transport’s favor.

It would also be interesting to include usage costs associated with each mile range. I figure a bus pass for a 20 mile trip is a lot cheaper than loan payments, gas, and maintenance for a single passenger car ride.
