Found this online regarding the Westchester Incident (via an article on comicbook.com

Spoiler:
Along the way, we eventually find out that Charles was involved in a horrific incident in Westchester County — where his X-Mansion/School for Gifted Youngsters is located. It's alluded to that Charles suffered a seizure and accidentally unleashed a powerful psychic blast that left 600 people severely injured (with some of those probably being his young students) and accidentally killed seven of the remaining X-Men (except for Wolverine).

Since we are never shown the incident, we are left to imagine how that tragic event played out. However, early drafts of the script actually included flashback sequences of the incident. So why were they left out?

"It actually hits home a lot harder than the versions that really painted out specifically the flashback," co-screenwriter Michael Green told The Hollywood Reporter. "Of course there are versions we wrote that were never filmed with the actual flashback of what happened, but I’ve found the experience of watching it is far more poignant to just know that it was something really regrettable and it was bad and most likely, friends were lost. Or maybe it was people we didn't know."
