Every time I see this happen you discover that tree was already damaged on the inside, like in your pictures.
I saw a program recently where a tree breeder talked about the shorter cultivars that the industry has been developing for a few decades now. They are bred to grow only about 15 or so ft tall, and MUCH better for city/suburban homes, instead of the ones like this, that tower at 20-30 ft and do all of the house damage that we see after storms.
Still, it hurts to see an old friend go down like this, just not go down on YOU!
Btw, I use my reciprocating saw every year to chop down saplings, and when they get tall and rangy, only about 2 1/2 inches in diameter, I make sure to saw off the top halves first. I have been knocked on the head before taking even these down at ground level. These big trees are SO HEAVY.
