"The Power of S.H.I.E.L.D.!"
Fury finds a way to signal S.H.I.E.L.D. without a radio, delaying disaster. But after Sitwell realizes Fury is the pilot, he still orders the launching of a "Strato-Mine", which could ignite the very atmosphere.
Supreme Hydra gets news that Laura Brown-- the daughter of his predecessor, who turned traitor and helped Fury a year before-- has been captured in Egypt. Donning a new disguise as "Emir Ali-Bey", he leaves in his "Hover-Limousine" to reach there by nightfall.
As he departs, he thinks that Fury will die without ever learning his true identity. Fury manages to turn the plane around, and, discovering where the Overkill Horn was hidden, dives from the plane, to be picked up by a S.H.I.E.L.D. submarine.
The plane-- followed by the Strato-Mine-- obliterates Karnopolis, its HYDRA base, and all within. Soon after, Fury and a S.H.I.E.L.D. squad rescues Laura from more HYDRA thugs.
Tony Stark congratulates Sitwell on a job well done, while Fury worries that the Supreme Hydra is still on the loose.
