Interesting thought about ejector seats, though those currently use solid fueled rockets iirc, as much safer.

Though it does as you say, offer some form of assisted powered control decent option. Not sure on the altitude and I know that becomes a factor for jets. Big difference operating around sea level and a few thousand feet up.

For me, something like this that would give firefighters the ability to reach and rescue people trapped up high in a building, even if one at a time. That truely opens up progress.

Alas the fire services have never ever had the same RnD budgets of military services, which is a thought that opens up a whole raft of debate as an indictment upon how we view protecting lives and assets - given fire in the modern world kills more people. For example in the UK in you get around 300 deaths a year due to fire. Compared with an average of 50 lives a year military wise. Though it is a bit like comparing apples with pears, it does make you think how some priorities are more grounded in history than others.

Now what this might open up as a viable alternative to parachute would be helicopters that tend to operate at altitudes that preclude any parachute. Sure you would need to eject the rotor and seen that upon military helicopters, that eject the cockpit. But this might open up safety upon more commercial offering.
