They could drop the load on the captain before Titanic sailed off. That would delay the journey and probably save it from the incident (if we of course don't take into account insurance scam conspiracy)

It's probably a reference to radio parts. Their radio was down for a lot of time, and they missed iceberg warnings issued by other ships.

At the time, probably nothing. At best they could have sent out life jackets or something similar, though I don't know how much they weighed at the time.

But if that happened today, we could minimally start getting inflatable lifeboats out to the people, supplementing afterwards with blankets for heat, life preservers, food, and so on. If you kept some on the ship in a slightly similar tragedy, the drones could offship as the sinking is happening and then immediately deliver goods to survivors. This last option seems more useful.

Not to mention it was 600km (370 miles) off the coast of Newfoundland, and took less than three hours to sink from hitting the iceberg. So if you happened to have drones in exactly the right place (assuming they’re based at an airbase on land), and sent them right when the ship started sinking, they’d get there just about as the last part was going under.

Exactly what I thought - the Titanic had radio/flares/lifeboats all of which seem more useful than a drone.

Flotation devices.

They wouldn't save the boat but could help people in the water and don't weigh much.

Not sure the technology then for self-inflating boats for people to get out of the cold water, but today you could make self-inflating rafts under 20 pounds.

I think many things we have today, would have saved the Titanic back then...
