BBC Four: If it was not accidental, are there any particular theories you find most compelling as to why the Liberty was attacked? JH: For the life of me I don't know. I don't think any of our guys do. The Israelis have got to tell us. There's a lot our government can tell us too. For our government to tell their planes to abandon us - evidently they had to have known something too. We know that there are still a lot of top secret classified papers from the National Security Agency and other organisations in the States. Hopefully those will hold the answers. I don't know what was on [President] Johnson's mind. I have no idea if he was talking to Israelis. That's why we need an investigation. We need to pull all the papers together.
BBC Four: Do the people from the Johnson administration deny that they recalled the flights? JH: They don't deny it. They won't talk about it. [Johnson's Secretary of Defence] Robert McNamara, who was part of the cover-up, recalled two of the planes. He conveniently says he doesn't remember. Other times he says, "I don't know" and other times he says "I'm not going to talk about it." He knows something - he knows an awful lot. President Johnson - he had to have known at the time and there are still other people around that know why this happened. There are laws against abandoning someone under fire and that's exactly what McNamara and the Johnson administration did. We were under attack for nearly two hours. For the first nine minutes they didn't know but after that they did not send help. Not that we didn't ask. We asked for help.
BBC Four: What sort of campaigning work are you and the other survivors doing to get people to look into this again? JH: We're at it every day. We write our letters, we talk to people, we tell our story, we tell them to write to Congress and ask for a congressional investigation.
BBC Four: Do you have any support in Congress? JH: Within the last couple of months there have been three congressmen who are aware of the situation. Of course I'm not going to tell you who they are but for the first time in all these years there is some interest there.
