There are multiple advantages on strapping the spot to your parachute rather than attaching to the glider. Not only you will have it with you if you bail out, but also in a crash it will be easier to activate the sos button when it is near you. I did some test early on and found no disadvantage when strapping to my parachute. In a reclined position it is 45 degrees which is good enough. I urge everyone to strap spot/InReach to their parachute.
I think this unfortunate accident proves how well our electronics improve the chances to be found quickly. Without it, it could have taken weeks or months to find Joe, not 24 hours. I don't know if it was flarm or spot which pinpoint his location, but I think it did great job. Of course there is room to improvement, such as InReach , but we are already ahead of the airline industry which still can't find MH370 after more than a year.
My condolences to Joe's family and friends.
