I think the song is referring to a girl who goes through guys quickly and never lets anyone break down her walls (I can relate!) and I think the song is saying that it takes something as tramatic as an impending plane crash to break down her walls and get her to say the deep down heartfelt feelings like "I love you." And as usual, with all of 3eb songs, there's always double meaning to the lyrics, so at the end for example, "It's coming inside" refers literally to the water rushing in and metaphorically to him finally breaking down her walls and getting inside her. With a side of sexual meaning as well (I remember Deep Inside of You)
