You know what would have been much more logical? Since he wanted to save Happy so much, Hiro could have delayed the exploision abit and allowed for him to carry the guy farther in the air.

So when Happy was flying in the air with Jackal, he would've had more time to let him go and then, in a immense burst of speed, just fly down. That way, when Jackal exploded, Happy would've just been sent flying farther its strength and not engulfed completely. He would've then smashed in the ground, receiving a great amount of injuries which could be life threatening, leaving Natsu with the increased motivation to destroy Tartaros.
