Here's a few bits about what has been done in a new article from D23 -
"The newly repainted plane with updated wing edges and windows will be on view along with never-before-exhibited items from the aircraft’s interior, including a customized instrument panel originally located near Walt’s favorite onboard seat that allowed him to monitor flight conditions; a telephone handset that gave Walt a direct line of communication to the pilot in the cockpit; a flight bag featuring an image of Mickey Mouse sitting on the tail of the iconic plane; and more."
"Disney fans attending D23 Expo are invited to shop, browse, and play at Amazon’s immersive space on the showroom floor with in-person peeks at custom merchandise related Mickey Mouse One: Walt’s Plane."
Walt Disney’s Grumman Gulfstream I plane will be on display for fans attending the sold-out D23 Expo 2022.
