To Edward Sandstig Do those reports really contradict each other The report referenced to by AirAttack  says that the ejection mechanism is activated when the gforces are high enough The report you bringhttpwwwsrsecgibinekotartikelaspartikel claims that the ejection handle was inadvertently activated by the gsuite which would expand acting on increased gforces In any case I think it should at least be mentioned that the pilot claims that it was the cause of the incident
