Expect to see a reply here every time this happens, since it would seem like it can’t be said/written/shouted enough:
Crestline is a P3 launch. Regardless if you have a site sign off from your instructor, you MUST NOT LAUNCH there unless YOUR INSTRUCTOR IS PRESENT.
Yesterday, another P2 launched into conditions that they weren’t prepared for and got lucky. If you’ve got a burning itch to fly Crestline, talk to your instructor and work with them to do it safely (and under supervision).
