. This experimental configuration aimed to evaluate the spacecraft's resilience during reentry and assess potential attachment points for future catch mechanisms2
. The changes included:
- Removal of heat shield tiles around the forward flap and other strategic locations
- Introduction of new ablative materials as a secondary protective layer3
- Testing of stronger heat tiles, reportedly twice as strong as previous versions4
- Implementation of improved adhesives for better tile attachment3

. This whimsical addition not only provided visual confirmation of the spacecraft entering microgravity conditions but also injected a lighthearted touch to the mission. The banana was not intended for deployment into space, instead remaining securely stowed in Ship's cargo bay throughout the flight3
.
To complement this banana-themed flight, SpaceX launch commentator Kate Tice sported a T-shirt bearing the phrase "It's Bananas!" during the mission webcast4
. This creative approach to demonstrating zero-gravity conditions follows a tradition seen in other spaceflight programs, where small toys or objects are often used as simple yet effective indicators of the transition to microgravity environments.4 sources
