query: What was the Cali Cartel's second plot to kill Pablo Escobar?
answer: The second plot involved bombing Escobar's prison using a surplus A-37 Dragonfly jet bomber and bombs illegally purchased from an El Salvadoran general.  The plan was ultimately aborted after a botched bomb pickup in El Salvador was exposed.
