David Shank, a retired U.S. Army colonel and expert on military rockets and missiles, said the large fireball captured on video at the hospital could potentially be explained by the fact the malfunctioning militant rocket impacted prematurely and was still full of propellant. That highly volatile fuel then ignited when it hit the ground, setting off a large explosion but leaving a relatively small crater. 退休美國陸軍上校、軍用火箭和飛彈專家大衛·尚克表示,醫院影片中捕捉到的巨大火球可能是由於發生故障的武裝火箭過早撞擊且仍然充滿推進劑這一事實造成的。這種高度揮發性的燃料在撞擊地面時被點燃,引發了一場大爆炸,但留下了一個相對較小的隕石坑。
