Maybe they are telling us that they got into space in the end. They carried on there journey using the solar energy of the sun to manifest in the form
of orbs. This fly by is a signal to their colleagues that the ill fated crew of STS-51-L finaly made it into space.
hmm, I do find it quite interesting that there are 7 objects in view.
and how there is 7 stars on the insignia as well.
but why would they make a formation?
I have never seen or heard of more than 3 orbs in one setting.
let alone 7 making a geometrical formation.
