AH! dv8 there I can shed some light on you (I'm a SEL Private pilot) the number one reason pilots hit mountains is 'WEATHER', there is no radar to warn you if you're gonna hit a mountain and shitty weather tends to cut your visibility to zero or blow you the fluck of-course.
Yes there is pilot error involved in most of them but also the weather is mostly unpredictable and obeys Murphy's law.
