I could cut the first part out but as it is there's the option to watch, skip or not bother at all ;-) I guess they were also doing a (lengthy?) preflight check, for instance you can see the pitch angles changing and I found in interesting. It was an unexpected event that I thought was worth sharing (videos aren't monetized).
Rather lengthy pre-flight check I guess (notice the person in front) when they were not in a hurry to leave. I had no idea but good comment for people wanting to skip to the action :)
