Ukraine Airshow Disaster - Sukhoi Su-27 Crash 3

Investigators suspect pilot errors, engine failure or plane overfueling (causing the plane to become heavier and less agile) as the cause of the crash. Both pilots ejected and suffered minor injuries.

This crash remains the deadliest ever, claiming the lives of 583 people when two 747s collided on a foggy runway on the island of Tenerife in the Canary Islands.
