This is a remarkable clip. Watch this footage of Jane Pauley interviewing Billingsley on Today the next day following the explosion:
Billingsley is so poised that you almost don't question the tastefulness of interviewing a kid--even a seasoned pro used to being on camera--about one of the most traumatic events of the decade--one he saw in person, no less. But I do. I don't really think it was a great idea, but full credit to Billingsley for pulling this off.
Notice how at the end he deflects an opportunity to puff up his own role in the YAP, staying "on message" and emphasizing the larger aspects of his role and avoiding seeming at all immodest. It's kind of a thankless spot for Jane Pauley, too, but I think the segment ends up being as tasteful as it could have been, all things considered.
