Something that seems interesting to me is that they all ejected at nearly the identical time. I'm curious if those systems are automated in case of scenarios like an unconscious pilot. If so, there may be automated clearance/angle systems, but that's speculation on top of speculation.
I'm guessing they coordinated by voice so that they didn't hit each other (again). If one ejects, then the plane rolls, the next person to eject could launch into someone else.
