That was quite an "adventure", if I may say so. With the injuries you sustained, it looks like you're going to need some time to get back to 100%, so I wish you the best in your recovery.
When you're able, could you tell us a bit more about what happened? Where, what aircraft, and what altitude? What happened to the engine? Why the ejection through the windshield? What happened to the seatbelts? Did the aircraft flip over on its back or did it stay upright? How long did it take the aircraft to sink?
Yes, I've been on a dunker course too. Over water I'm wearing a lifejacket and for long legs even a survival suit plus some locating geat. So I like to think I'm prepared. But still, I'd like to learn everything I can from others, if that means I don't have to experience it myself...
