Piano hinges with cable instead of wire hold the pod to the rest of the
airframe. Size it to resist the canopy lift load. When you pull the
plug, a spring-loaded reel yanks the cable out. The chute deploys, and
the airplane falls away from you.

Best let go of the stick, since the controls are attached to the
airframe. All that's in the pod are the seats (strap in tight!). The
control panel needs to stay with the airframe, too - waaay too many
quick-disconnects to think about there. One set for the headsets is
doable, but throttle, instruments... of course, with FADEC and a full
glass cockpit all you have is a big honkin multipin plug. No. You
still have the steam gauges as backups, so you still have the
pitot/static connection to deal with.

But now you don't have any structure under you to cushion the impact.
In fact, your feet are hanging out in space a la Fred Flintstone.
