On the fuel uplift point though, I thought it was safe airmanship to have enough fuel to get you to your destination OR your alternate, including a hold of 5-10 minutes, and still have 30 minutes reserve on landing. So O'Leary's policy of getting pilots to justify higher fuel loads seems counter to this.
In clear skies, efficient airport and outside of rush hour, yes, it is sufficient. However, none of this existed during the night in question!!
