The million-dollar question has never been whether the objects are present on the plates.
I do sort of wonder whether the features on the reproduced images of the plates identified as transients by Solano, Villarroel et al. are actually all present on the original plates, and if some methodological error or reprographic process might have caused an under-representation of such features within Earth's shadow (or an over representation elsewhere) when studying the reproduced images.
