Absolutely. That and the fact that the senior pilot wasn't listening to his co-pilot and didn't feel like he needed to.
Yes but the primary cause of the Tenerife disaster (a collision on the ground with one 747 taking off and another one crossing the runway) was poor CRM in the cockpit of the departing plane, with bad visibility and multiple incidents as contributing factors.
IIRC, it wasn't caused by the inexperience of the tower controller, or them being distracted, etc.
