Icepops gifts Baby Goose a two-seater plane, just like he did for Mav.
"Good to have you back, kiddo."
After THE talk, Bradley shyly asks Mav to help him repair the old bag of ass, and it's going to be their dad & son project, their bonding therapy.
Then, Bradley and Ice handle the artistic customisation of the plane. It at some point evolves into a paint war in Mav's hangar.
(Dadmiral COMPACFLT is ruthless.)
"WHO THE HELL PUT PAINT ON MY KAWASAKI?!"
When The Rooster is finally done, Bradley is in the pilot seat, waiting to see who's going to be his RIO/WSO. He has to plug his ears, because his dad and pop's bickering ends up being about who's going to offer the best sexual favour in exchange of being the first to fly with Bradley.
"Ugh. Why me?!" he complained fondly, bonking his head repeatedly on the window pane.
The third person privileged enough to be Bradley's backseater, is Hangman.
As a 'thank you for saving our lives, I knew I was right to make you the Spare', he was invited at the Hangar to go nerding with Mav about the P-51.
What happens is Bradley going all smoothly with -
"Fancy riding the Rooster?"
Also Jake gets to see THE pictures on the hangar walls, including baby pictures of Bradley, and 'holy shit, is that...'
