First of all... That does not look like a C-130 in that photo... Secondly... C-130’s are among the safest and most reliable aircrafts ever created. For the wings to fall off a C-130, it would take a major error on the part of the maintenance crew.
——major error-——
A much higher probability would be sabotage
See post #14. It appears everything in front of the wings plus the tail section with part of the fuselage fell off.
It also has a link to a similar incident with a USMC C-130 from 2017.
