So what about McGonagall? The Time Turner? She's suprisingly absent and very cool about the whole situation, at leaat in the movie. She could easily go back arresto momentum save Dumbledore from the fall, maybe even have dumbledores future body brought back and laid dead. I mean if he falls from a high Tower he's gonna be pudding and meat on the ground not just have a bloody nose.
She could also have given Snape am anti venom and had a nurse or even fawkes revive him with the healing powers as shown in the second movie. Which is also the one that brings the time Turner and the miracle bone re grower. McGonagall could have gone back to save them or even help Dumbledore orchestrate everything. They could be alive or have taken over people who died long before McGonagall had a chance to save them
Don't be silly, time turners are best used to allow teenagers to take an extra class.
The killing curse is what killed Dumbledore, cushioning his fall wouldn't do anything. He was dead before he even started falling. Plus what is the point? Dumbledore was going to be dead within a year anyways. At least this way of doing things allowed Snape to remain working for Voldemort.
Fawkes can't revive the dead.
