One thing I wanted to add about the Snowbird crash that I learned about years ago.
I thought about it when I saw the picture of the one pilot on the roof of that house who got injured and was being helped by others.

The ejection seats in those jets are a last resort and I had heard that it can be a very violent exit from the plane. A person can be injured by the ejection itself. The seat of the plane literally has to be jettisoned up and away from the plane with force. Then once in the air, the person has to be jettisoned away from the seat. I think it is basically small explosive type or small rocket engine type devices that cause those things to happen and it can be a very violent exit.
The bottom line is you dont want to pull the ejection release unless you know its the last resort. They obviously realized they had to get out of the plane. Unfortunately there was not enough distance to allow the 2nd person's chute to open in time before the ground came upon them.
I am pretty sure the one who landed on the roof had a rough impact too. Just glad at least one of them survived and I hope they recover fully.
I had a friend that used to parachute for fun and I got to learn about how parachutes work and he showed me how he packed his. One thing I found interesting. My friend would never allow anyone to pack his chute. He always did it himself and I suppose that makes sense.
The ejection seats in the plane of course already have the parachute as part of the ejection seat so its not like they packed chutes for themselves. It is more like a car air bag system where the chute would always be packed with talcum powder or something that keeps it from sticking to itself so that when an ejection is necessary the chute will open ok.
Maybe there is a yearly check of it or something along those lines but I am pretty sure its all part of the ejection seat mechanics and is not something they typically would ever have to use.
Thankfully the ejection seats worked as designed. They just needed more altitude unfortunately. The ground came too fast for the chute to open properly.
