Depending on speed probably less than a second to reach a 60 degree bank but nobody flies that way because the engines and pylons aren't built to take those forces so even test pilots don't do it. They may withstand it but nobody flies like that. Tell your conspiracy friends about the 9-11 Pentagon crash that it didn't make a 10G turn but vaporized. That is the only explanation for not seeing it depart at high speed. I wonder after the 10 G turn where they were going?
