It happenned to me on what would have been my second AFF jump we were 2 AFF students with the rest of the load being tandems. We are all getting ready to exit the plane all equipment has been checked I just put my goggles on, green light just came on, I get ready to take position with my instructors right after a solo got out of the door then my instructor held me back and told me to go sit down and buckle up because the winds at ground level were too high for our canopies. So me and Kim(the other student) rode the plane down with one instructor while the other three just enjoyed their free jump. Mind you I still had a great time because the pilot is a thrill seeker he made the plane dive so much that we ended up getting 3-4 seconds of weightlessness. I came out of that plane smiling almost as much as if I had jumped.
