Underwear bomber was 2009, and if you search for 'aircraft passengers restrain' you'll find many other stories about passengers acting against dangers on flights.
Hijackings used to be common, they're not anymore post 9/11. There were 27 hijackings in 2000 worldwide. There were none in 2017, 1 in 2018, etc.
While that may be a factor, there's never any news about this happening, except maybe shortly after 9/11 with shoe or underwear bombs.
