Before the conspiracy theorists get too carried away, it is of course equally likely I'm afraid that Sascha went down still strapped in his seat, together with the central part of the fuselage, though we don't know which bits they recovered, other than side panels with the KA reg on. If the engine were still attached to the cockpit floor and seats, it would all sink like a stone. So technically he is missing unaccounted for unless a dive were carried out to confirm one way or another, that's for the insurers and police I guess.
As operated in FreeFlight (KA only recently transferred out), all the SR22s had a 406 MHz ELT (activated manually or on violent impact), a 4-person liferaft, 4 life jackets, mode S transponder, Skywatch, TAWS-B terrain awareness, lightning detection, a specialised hammer to smash an exit in the side windows, and of course Autopilot, leading-edge icing protection, CAPS and air bag front seat belts as standard. They cruised comfortably at 150-155kts which would certainly be dis-orienting if majorly out of stable flight. Sadly there have now been a few instances of CAPS pulls not working correctly and if only partially deployed it would be pretty terminal.
If they recovered the MFD this would have a recording of all the major flight parameters leading up to the incident, not sure how long that could survive for though. KA wasn't a G3 that additionally have a flight data recorder fitted.
