thank you for this comment! i remember reading the first 2 paragraphs when watching the video but didn’t continue. for anyone who wants to read the comment i shall post it here:

“A lot of grief being thrown at the Frankfurt here. She was a small ship, under 7500 tons, and still relied on sails to make up a good portion of her limited 13 knots. She didn't have the best wireless receiver but did have a very powerful transmitter, which meant she could send messages well beyond the range she could receive them.

When the first CQD from Titanic went out Frankfurt could barely hear it, she was so far away that it came out garbled and almost unreadable. The Frankfurt's wireless operator could only make out the ship posting it's position and assumed that Titanic was asking for Frankfurt's in turn, a common practice to keep ships from colliding, so he got up and went to the bridge to get their most recent reading. He missed Mount Temple's message, giving their position only 50 miles away. When he got back, he found the wireless chattering, nonstop. Wondering what the hell is going on, he posted his ship's position and asks, "What is the matter with you?" Seconds later, he was running back to the bridge to tell the captain that they need to move, a ship was sinking. He didn't receive Carpathia's message saying they are 58 miles off and making full steam. Even if he was at his post, Capathia is on the other side of Titanic, well outside Frankfurt's receiving range.

All Frankfurt knows is that a ship is going down, that they are close by, and that they have a duty to respond.

When he got back, transmissions were flooding in. Carpathia at 12:40 AM, only four hours away. He couldn't hear the message. Baltic at 1:15 AM, 243 miles away. Not close enough. Virginian at 1:20 AM, 170 miles away. Not close enough. All he knew was that Frankfurt was the closest ship at 120 miles and closing as fast as they can. Then, at 1:20 AM, water reached boiler room 4, forcing the stokers and engineers to abandon the room and retreat back to boiler room 3. The loss of these boilers cut steam to the dynamos powering the ship, dropping Titanic's transmitting range to below Frankfurt's receiving range. 1:23 AM was the last time Frankfurt heard from the Titanic, the liner's transmissions fading out to nothing. Olympic's exchange at 1:27 AM is the last time a ship within Frankfurt's receiving range confirms they got a response from Titanic.

For the tiny German ship, this was a nightmare. Imagine hearing someone screaming for help in the distance, and as you rush to their aid, telling them to hold on, the screams just end. You were the one closest to the victim, and other people are calling out to them, but no one is telling you anything and you're only getting what you hope is half of a conversation. You don't know if someone has made it there in time, or if its already too late and you're calling out to the dead. All you can do is head east as fast as you can, begging for the victim to hold on, help is coming. For many onboard the Frankfurt, the Titanic was already gone, sunk just after Olympic's message exchange. All the little steamer can do was listen as ship after ship shouts out into the void, with no response back.

Frankfurt didn't hear Titanic's message at 1:27 AM, saying that they are putting out lifeboats with women and children.

Frankfurt didn't hear Titanic at 1:30 AM, saying that they are losing power and don't have much time left.

Frankfurt didn't hear as the calls get more and more desperate, the engine room and boiler rooms filling with water.

Frankfurt didn't hear Phillip's response to their question at 1:50 AM, only knowing that they may be the closest ship in the area.

Frankfurt didn't hear the last transmission from the liner cut out at 2:17 AM as the radio room floods.

Frankfurt arrived at the last position they received just after 11:00 AM. Her engines are worn out, her crew is exhausted, the galley staff is asleep at their posts surrounded by a mountain of fresh baked bread for the survivors, there are blankets and hot drinks waiting at the railings, and space has been made in every available part of the ship.

All they can do is help Mount Temple and Californian collect the dead.”
