In the English-language Thai media? Lack of information across the board would be my guess. Police and army choppers fall out of the sky here regularly and the authorities are tight-lipped. Nobody reports on any investigation or follow up. If the local media can't get any more information, there's likely to be little effort for foreign media to pursue it.
Ships of all sorts have accidents, run aground, catch fire or blow up daily. It's all in the maritime media but it doesn't get much beyond that unless it blocks the Suez Canal or a US Pacific Fleet boat is involved. They quite recently had a destroyer run aground off the Philippines. It was so badly damaged, it was written off and salvaged in bits. Didn't get much media coverage though. Of course when there's loss of life, it can become more visible.
