And the guy asked me if I've got any Al Qaeda background, and I went, 'no'".<br/> The spectacle drew many onlookers as well as families members who watched the rescue with bated breath.<br/> (SOUNDBITE) (English) DAUGHTER OF RESCUED PASSENGER<br/> "When the fuel went down, I thought the airplane was going to explode."<br/> The plane's passenger said rescuing the children was the first priority.<br/> (SOUNDBITE) (English) RESCUED PASSENGER, JOHN, SAYING:<br/> "We hoped we hadn't hit no one, like, seriously injured no one. That was our main concern. Then, when we found out we had kids, you know, I think it was in the one next to us or a couple down, it was like no, get the kids out first. Don't worry about us. Just get the damn kids out."<br/> Cox was practicing maneuvers at a nearby airstrip.<br/> Authorities are launching an investigation.<br/> Jessica Gray, Reuters
