The dinosaur sequence was credited to Jack Harris, and used a dinosaur model that he created for the 1961 film Dinosaurus. The model was filmed on a tabletop diorama for two brief shots. At $2,500, they were the most expensive shots during the series' run.
Narrator: You're riding on a jet airliner en route from London to New York. You're at 35,000 feet atop an overcast and roughly fifty-five minutes from Idlewild Airport. But what you've seen occur inside the cockpit of this plane is no reflection on the aircraft or the crew. It's a safe, well-engineered, perfectly designed machine, and the men you've just met are a trained, cool, highly efficient team. The problem is simply that the plane is going too fast and there is nothing within the realm of knowledge or at least logic to explain it. Unbeknownst to passenger and crew, this airplane is heading into an unchartered region well off the beaten track of commercial travelers. It's moving into the Twilight Zone. What you're about to see we call The Odyssey of Flight 33.
Captain Farver: Hold it. Hold it a minute. Did you feel anything?
First Officer Craig: Feel anything? No. What do you mean?
Captain Farver: I don't know. I felt something. Something funny. Like a sensation of speed. I can't put my finger on it. Guess I'm getting old.
First Officer Craig: True airspeed 470. We're level. Suppose we picked up a tail wind?
Captain Farver: Yeah, maybe. Those jet streams are tricky. It's that crazy feeling I can't shake. You can't feel a tail wind but I feel something.
First Officer Craig: Everything looks fine.
Captain Farver: Magellan, try and get me a ground speed check with the Doppler.
Navigator Hatch: Indicates nine hundred. That's impossible. I'd better check with Loran.
Janie: What's going on?
Navigator Hatch: Hold it a minute. Skipper, Loran indicates a ground speed of 830 knots. I never heard of a tailwind like that.
Captain Farver: Check it again. See if you can raise the weather ship Charlie.
Second Officer Wyatt: Yes, sir.
Captain Farver: Ask them for a radar fix on the ground speed check. Magellan, are you sure about that ground speed?
Navigator Hatch: I'm not only sure, but we're still accelerating. 980 now. 1120. 1500. God in heaven, I can't even keep up with it.
Second Officer Wyatt: (Into the radio) Global 33 to weather ship Charlie. Global 33 to weather ship Charlie. Captain Farver: What about Charlie?
Second Officer Wyatt: Nothing, sir. I can't raise them.
Navigator Hatch: 2100.
First Officer Craig: Oh, I hope the wings stay on.
Captain Farver: They will. Don't worry about the wings. It's the true air speed that counts. Ground speed means nothing. Well, we just hit one lulu of a jet stream. Magellan, my needle just reversed past Gander VOR. How could we get past-? Get me a fast position check.
Navigator Hatch: Skipper, we are past Gander. We must be doing three thousand knots.
Captain Farver: Try to raise Harmon control. If you can't raise them, try Moncton or Boston. At this speed, you might as well try to get Idlewild.
Second Officer Wyatt: (Into the radio) Harmon control, this is Global 33. Harmon, do you read us? Moncton. Moncton, this is Global 33. Boston. Boston control, this is Global 33. Boston, please acknowledge. Idlewild. Idlewild, this is Global 33. Idlewild, do you read us? No soap. I can't raise anyone.
Paula: I'm seeing The Valkyrie tonight. Oh, Janie, I've always had a thing about Valhalla. Be a good egg and tell me I'm going to make it in time for the curtain.
Janie: Let me put it to you this way. I only hope the Valhalla you're talking about is at the Metropolitan Opera House in little old New York.
Paula: Instead of?
Janie: Instead of a conducted tour through the real thing.
First Officer Craig: Skipper, do you know what that is?
Captain Farver: I know exactly what it is. It's the New York World's Fair.
Second Officer Wyatt: New York World's Fair? But that means we'd be back in...
Navigator Hatch: 1939. We came back. We came back...dear God, not far enough!
Captain Farver: Can't land. Can't land at LaGuardia. Can't land in 1939. We've gotta try again.
First Officer Craig: Well, what about the passengers?
Captain Farver: I think we'd better let them in on it. (Into the cabin PA) Ladies and gentlemen, this is your captain. What I'm about to tell you...what I'm about to tell you is something I can't explain myself. Your crew is as much in the dark as you are. If you look out on the left-hand side of this aircraft, you'll see directly below an area called Lake Success. And those buildings aren't the United Nations. They happen to be...they happen to be the World's Fair. What I'm trying to tell you is that somehow, someway, in some manner, this aircraft has gone back into time and it's 1939. We're going to try to increase our speed and go back through the same sound barrier we've already done twice before. I don't know if we can do it. All I ask of you is that you remain calm and pray.
Narrator: A Global jet airliner, en route from London to New York on an uneventful afternoon in the year 1961, but now reported overdue and missing, and by now searched for on land, sea, and air by anguished human beings fearful of what they'll find. But you and I know where she is, you and I know what's happened. So if some moment, any moment, you hear the sound of jet engines flying atop the overcast, engines that sound searching and lost, engines that sound desperate, shoot up a flare or do something. That would be Global 33 trying to get home from the Twilight Zone.
