* In a blink and you'll miss it scene near the end there's these two kids. Both pretending to be the Rocketeer.
* Valentine, of all people, wishing the Rocketeer good luck.
** And also the fact that he may not make an honest buck, but he's 100% American.
* Towards the end, when Hughes asks Cliff what it was like flying with the rocketpack:
-->'''Cliff:''' It was the closest I'll ever get to heaven, Mr. Hughes. (''glances at Jenny'') Well... maybe not.
** So after all Cliff did, Howard Hughes gives him a new Gee Bee airplane in the end.
-->'''Cliff:''' I didn't even get a chance to thank him.
-->'''Peevey:''' You don't have to, son. He saw the look on your face.
