So, is it safe to say that it is a good thing these astronauts are back on earth?? Yes! And is it safe to say thank you to Elon Musk and SpaceX helping make that happen?? Yes!
I read through all the events and how they occurred including the statements made by the astronauts, and from their perspective they have no idea why there was a delay and that they were "not privy to any discussions as to why" and/or if it is "political", but they indicated that it didn't matter to them because they were prepared to stay as long as they did as that is part of the preparation prior to heading into space originally...i.e., they were prepared to stay 8 days or for as long as they did.
