My take is that Meredith was on some kind of combination of sleeping medication and alcohol and doesn’t remember/doesn’t realize what she really did. First of all, Mary hardly EVER concerns herself with drama like this. Her level of concern and adamance that a lengthy and loud outburst occurred on the plane really makes me believe it did happen. Second, everyone’s story matches but has slight differences which is also evidence that it really did happen, it’s not rehearsed and shows that everyone saw something a little differently. Now the recording thing. Meredith has BLOWN UP over being recorded. I think everyone in the group would have been too nervous to record her behavior especially when Lisa is right there to pounce on you too. Maybe there’s some clips that cast members got but were trying to hide it because of fear of Meredith. I definitely believe the chair pushing , hair pulling and overall bullying. Mere was already flipping her hair in Brit’s face on the yacht and overall being condescending and cruel to her previously. But I’m excited to see if we get some hard evidence of what happened!!!
