As of this writing (6/2006), there are no user comments on the IMDb for this production. Based on that fact, I assume it may never have aired again after its initial 1977 broadcast. If this is the special I remember having seen on live television back in 1977, its lack of re-broadcast does not surprise me. I'll add my memories of it here from a distance of nearly thirty years.
My recollection is that this was an hour-long, primetime network television special. I seem to remember it airing from 9 pm to 10 pm on the East Coast. The hosted portions of the show were live. As I recall, the special was to feature three or four different daredevils each performing an individual stunt. The headliner and final stunt on the show was to be Evel Knievel's live attempt to jump a motorcycle over a pool filled with sharks.
Being a young boy at the time, I have vivid memories of the commercial that ran advertising this special in the weeks before it aired. The advert showed live sharks circling (presumably in this pool Knievel was planning to jump over), while a breathless announcer said in part: "
and if he doesn't make it, water wings won't help!"
The live broadcast itself was a let down. Although the IMDb lists Evel Knievel as the host of the show
it didn't happen that way. He was in fact lying in a hospital when the television special aired. Earlier in the day, Evel had made a practice jump over the shark tank and had crashed. I remember the hosts of the show appeared really shook up about it. Throughout the hour that the special aired, they kept passing on to viewers live updates from the hospital regarding Evel's condition.
Wide World of Sports did a follow-up story, not too many days after this special aired, that included an interview with Evel in the hospital. I believe it was mentioned that the indoor arena where the shark jump was being staged did not have sufficient space for Evel's bike to build up enough speed before it took to air which is why he crashed.
I also recall one other sad note concerning this special. One of the other daredevils that was to perform during the hour died. I can't remember if his death occurred just before this show aired, or just afterwards, but he was not killed performing for this particular production although he was killed attempting the same kind of stunt. He was an elderly gentleman who was famous as a tightrope walker. He fell while attempting to walk a rope strung between two high buildings, as I recall.
Overall, this TV special was kind of a let-down for the audience. It had been hyped as a live attempt by Evel Knievel to jump a tank full of sharks. But as soon as the show opened, they revealed Knievel had already made the attempt earlier in the day (albeit in a practice run). He had been so badly injured that the show's intended climax was cancelled
before it even began.
