As you can see, that's a lot of stuff to look at. Particularly right after landing, it gives you a pretty
good idea of what happened. For example, we did a test in which we intentionally didn't install a
drogue charge and left out the motor eject, and turned on FailSafe as a test. (We don't recommend
that YOU do this, though...) We expected the Main to pop 3-4 seconds after apogee, but that didn't
happen, instead it came out at about 500' as if there was a drogue. When we looked at the Flight
Summary data, it turns out that it never fell fast enough to trigger FailSafe... it was a light Estes
rocket on an Aerotech F24, and the drag was enough to slow it down below the threshold.
We've had other flights in which we had FailSafe enabled as a safety measure, and it triggered when
we though it should not have. Turns out the drogueless rocket fell faster than we expected...
obviously we should have modeled it better! All of this data can tell you a lot... and help you model
your later flights better.
