The Infiltration into Zephyr One was a planned takeover by Sarge's Squad to take Zephyr One and leave Earth's atmosphere before they were caught in the explosion from a Atom Bomb that was about to destroy a Shrike Tower and its creator, Izel. After the tower was destroyed, but the explosive didn't go off, Izel fled in the Lazy Comet, causing Sarge to change tactics and force S.H.I.E.L.D. to chase after her.
"We're not on their base. We're in their plane." "Even better."
"Take me with you. I've spent years tracking Izel, studying her every move... all for a chance like this. I have to do this. You don't understand what you're up against." "You're right. And that's why we're bringing Jaco along. But thanks anyways."
