Vox had a good piece on it a few years ago, and then the recent TV adaptation of Watchmen dramatized it in the opening scene of the first episode, including showing the fact that attackers use airplanes to fire rifles and drop firebombs.
I would add that this story with the discovery of a mass grave at an indigenous reeducation school in Canada is another example of terrible history people just don't know about (similar system existed in US).
