The ship was supposed to be 100nm out of Egypt and Israeli coast. It was 25nm. when the planes flew by, they had a drill in which the machine guns were manned. And for a pilot seeing that, it must have meant an enemy ship. Egypt were also known to camouflage their ships. Plus, no IFF like we have today. The ship was also sent information to stay away. So Israel actively and purposefully began attacking it thinking it was Egyptian.

Israel has apologized and paid massive amount of reparations. Only people who are into demonization of a country and grifters are still trying to milk this. It is like beating a dead horse over and over, and this will never stop.
