Avherald has an unconfirmed post about a Vietnamese AN26 search aircraft spotting an oil slick at N 7.55 E103.15. The post says it's from vietnamese news.
This would be 45 NM in direction 327 degrees from the last known position of MH370 reported by FR24, indicating some kind of flying ability after the loss of contact.
Let's wait and see if this is true or false.
