I would be pissed...the SOP is that the student should only be assisted if there is no indication of them initiating pull procedures by there designated alt. It sounds to me that the main side AffI was experienced(that seems rookie). It is all about reading the student and pulling for them only if they are below their hard deck.
I question the ability of the AFFI in a student going low situation. I sure hope that the AFFI is not afraid of going low with a student. Its not a matter of IF but WHEN.
this would bring up a new question for all you AFF-I's out there.. what is your hard deck?.. I mean really think about this... I didnt have a student go low on me until I had about 200 AFF's.. It was sobering. I re-evaluated my safety protocol after that jump and it has saved my students ass as well as mine.
