Reports are the ship was hit while traversing the Bab al-Mandab strait, in which case simple geography would have meant the ship had to get very close to the Yemani coast....
Why was this ship close enough to shore like this...and then at night you can see that some of the small boats taking pictures gt in retty close.
Potentially to within visual range depending on where this happened, so that video could even have been shot from shore rather than from a speedboat.
If that is true, it would simply be an astonishingly unforgivable elementary mistake to not see the obvious vulnerability of a ship in that position and assign it proper protection to escort it past that obvious choke point and danger zone.
Looks like they underestimated their foe to a ridiculous degree and thought that running with all nav lights off at night would be sufficient protection against detection and attack.
Some heads will roll for this, probably literally if members of the royal family died as a result.
The only potential bright spot from this unmitigated, self-inflicted disaster might be the timing of the attack.
With it being the middle of the night, most crews and passengers would be in their quarters asleep, that would have given them a far better chance of survival than if it was day and everyone was up and about.
Although this being the UAE, they probably converted much of the observation deck into penthouse apartments for the royals so they could enjoy the views from those massive windows, in which case that would have put those sleeping royals right in the middle of the most likely blast area.
