The worst part is there’s a lot of contexts that can be applied to his message, is he saying an hour and a half because that’s how long the flight is and he fears he will never make it? Or is he aware they are on their way down and actually potentially has made it to a life raft etc and hopefully can be found in time. I’m realistic enough to know the likelihood’s but you can see how the not knowing is the worst part for the family.
If you listen to the audio on Ole, he doesn't sound very scared, more a conversation in passing with some twinge of fear attached to it. Definitely sounds as though he's getting on the plane and is nervous.
