Hello. There is a picture of an airport lounge. It shows people doing different things. Behind the large window, in the far background, a plane is taking off and it is already in the air. I wonder how I can describe the action of the plane. 1. The plane is departing from the airport. 2. The plane is taking off from the airport. 3. The plane is flying away from the airport. I think I can say #2 and #3. What about #1? Isn't departing connected with a timetable only?
