A HERO cabbie who took on the Glasgow Airport terror suspects told yesterday how he booted one of them in the privates. Alex McIlveen, 45, kicked the man, whose body was in flames, so hard that he tore a tendon in his foot. But he said last night: "He didn't even flinch. I couldn't believe he didn't go down. "A doctor told me later I'd damaged a tendon in my foot."
