The planed landed at 3:33 PM? Think about '333' and its relation to the Freemason Compasses and its degree setting of '47'. New Mexico is the 47th State. The man's name, William Grubbs, connects to 'Freemasonry'.
Again, he was landing in the 47th state, New Mexico. New Mexico = 48; 223, the 48th prime
The article also says he was called Mike Grubbs.
Kill = 44; Execution = 44
163, the 38th prime; Death = 38; Killing = 38; Plane landed at 16:33
A part of me wonders if this is some sick tribute to September 11, 2001, where Flight AA-11 crashed into the 110 story World Trade Centers.
The number of the flight, 1353, factors into 3 x 11 x 41.
9/11/2001 = 9+11+20+01 = 41 (USA) (al-Qaeda)
