I heard some "expert" on BBC last night who questioned the accuracy of that alleged fact. Bottom line is that the facts are all up in the air (sorry).
Heard an FBI guy on Hannity say he ascribed this to chaos and incompetence from Malaysia.
And, fwiw - Hannity was at his absolute worst trying to report the story. He was trying to say that the Captain was emotionally distraught over the politician who had been on trial. I studiously avoid Hannity - I try not not have my intelligence insulted if I can help it. But, I bit on a Tweet from Greta.
Oh, the 45K ft information came from the Malaysian government? OK, then I can rest assured it’s false. They have done nothing but lie since this whole thing started.
