I did my AFF level 1 this morning, it was interesting. freefall went real good, everytihng went well untill pull time. I pulled fine, then nothing happened. the pilot chute was completly inflated but the pin was stuck. one of the instructors said it was really jammed in there and he had to give it a nice pull. i fell for another 1,000 feet while that happened. it was pretty scary but i cant wait to go for level 2.
