On my first AFF jump I was pretty nervous and maybe a bit scared. On the flight up my instructor had me going through my dive flow over and over again. I had done a tandem before, but this was the first time with a rig on my back.
I checked my alti (student loaner) and it was stuck on 1.5. I tapped it but it didn't move. Without thinking about what I was seeing first, I leaned back to my instrutor and said "Hey, this thing's stuck on 1,500!"
You probably guessed it...she looked at me strangly, then pointed in succession to the "11", the "0", and the "1" on my alti while saying "11,000, 12,000.....13,500".
Later on she told me it was one of the funnier things she's heard a student say, but at the time she was thinking "oh s*&^, what am I getting into?"
