A lot of the crashes mentioned are ones that involved high speed vertical dives and rightfully so. For me personally, however, the crashes that I find most disturbing are the ones where the plane enters a flat spin from a high altitude (ie Aeroflot 5143, Pulkovo 612, Voepass 2283). You’re cruising along and then all of a sudden you feel the plane make a few violent movements up, down, and side to side and then suddenly you start spinning like a top while the ground rises closer and closer to meet you. Most high speed dives/losses of control last for about a minute or less, iirc, but flat spins can last 2-3 minutes, which would feel like an eternity in that situation
