So That's Why There's a Banana on Starship

I learned only today why the art on the side of Starship 31 had a cartoon of a banana on it that was holding another banana marked "FOR SCALE."  It was because part of the test of the Starship was to carry a banana into space. For scale some reason I can't explain. The banana is quite visible in this photo inside the ship while it was traveling toward its reentry.

Little did I know that bananas are used as standard measuring sticks on some social media sites.  This is the entrance to the rabbit hole of trying to understand how bananas became a standard when bananas aren't all the same size.  They vary widely in size. Amazon sells a "standard" banana just for this. (As always, the link is for information only, I don't make anything if you buy the banana squeeze toy.) I recommend not trying to answer that.

Picture saved from the Amazon product page. I don't know if Starship carried this, a grocery store banana or something even weirder.

There are pictures on the product page showing this "Official Banana for Scale by Citadel Black - Stress Relief Toy," alongside actual grocery store bananas demonstrating that bananas vary widely in size. 

All that aside, I haven't had the time to search for explanations of why Booster 13 aborted trying to be captured in midair like last month's flight. The Ship's hovering and splashdown was much like last month's, but was supposed to have been pushing the ship's capabilities a bit more. The inflight restart of the Raptor engine seemed to have gone as planned and then vertical landing and splashdown in the Indian Ocean looked much like last month's. This time, instead of just having a camera on a buoy, there was a vehicle close enough to the spot to allow an aerial camera - or crewed vehicle - to photograph it.
