To be honest, I wasn't there to witness this event and am relying on my friends account of what happened, so I'm making no judgements here.
I haven't been involved in student training for a long time (10 years) so just wanted some clarification on current methods.
Whatever the AFF instructors decisions, weights, no weights, baggy jumpsuit etc. they should not lose their student.
I do find it interesting though that on a previous jump they (same DZ different instructors) saw fit to give her weights because it was windy and they thought that would help her penetrate under canopy... Again I wasn't there so not my place to judge but I do agree that giving a 45kg girl 5kg of lead and a 10kg rig is likely to increase the risk of injury on landing regardless of conditions....
As far as throw out or spring is concerned, I guess either way has it's merits and shortcomings, so it's upto the instructor in the end.
Thanks for the feedback,
Cheers
