Both Captain America and Bucky were on the outside of the plane, but it was Bucky who caused it to explode mid-flight thereby destroying the bombs it carried. This resulted in Captain America being frozen for years, and Bucky was believed to be dead. In reality he was actually undergoing a fate worse than death as he became twisted into the villainous Winter Soldier through years of endless torture and reprogramming.
