"The FAA alleges that during March and April 2013, National failed to comply with Federal Aviation Regulations while loading heavy military vehicles onto two Boeing 747 jetliners that the company operated. The jets were flown on seven flights while loaded with one or more Mine Resistant Ambush Protected Vehicles (MRAPs), each weighing between 23,001 pounds and 37,884 pounds."
My point is that perhaps up to two months prior to the crash the FAA all already warned them so yes IMO they kept playing "Russian Roulette".
