I´ve also re-read your previous post and think that Díaz saw the second Dagger of Plata while he was lying over ground.The first one, according to your description, had just passed while Díaz was still hanging in the air.
The key would be to know who passed first, Callejo or Musso?. Although Musso landed before, perhaps he passed by Callejo during his return, over the ocean. It´s probable that if Callejo had spent a lot of fuel (it seems he afterburnered), he would have gone up higher and adopt a lower speed to save fuel, so he could be passed by over the ocean.
And still don´t have Dellepiane testimony. More surprises still awaiting?
