It’s also possible the Tantive had just docked with the Profundity to render aid, and retrieve the plans?
I don’t think so I mean there is far to much Dialogue about the Tantive not only having a totally separate mission and going somewhere else and nothing to suggest they were going in to battle.
I could imagine the plan’s being transmitted to the tantive (Far away out of firing range) and as say the Death Star monitors that a transmission was being sent off planet because it’s on their own band width and they possibly could struggle to jam it and at that point the decision to fire on the planet is made.(Highest security Priority un-jammable signal)
Just as the plans are being uploaded and just as it completes sending the transmission the deathstar fires on the dish. But Too Late it got through…
Darth Vader then jumps in to the location of where the transmission is sent on the devastator.
Then you have the chase between the Tantive and the Devastator. As it is in the film a chase is not exactly possible until Vader trudges back to his shuttle flys back to the devastator then flys off to get to the Tantive. This does not make sense either.
I Like Raddus and all but I just can’t see any way of reconciling that Raddus and The Tantive IV and crew go together in any way shape or form. He is not important enough.
I can accept it but I know different.
Remember once you go Light Speed you never get caught.
