Lyrics with meaning

[Flint]

That might be obvious, but for years I thought this was a description of someone's father having an affair, overseas while in the military, and this mysterious lady becomes pregnant (the flowers bloom where you have placed them).

Of course, they go on to say:

Angels wings are icing over
McDonnell-Douglas olive drab
They bear the names of our sweethearts
And the captain smiles, as we crash

I guess I just picked out the first part and formed this strange romantic image of the author imagining his father with some other woman, who smiles just like mom, and raises some mysterious sibling somewhere far away. It's something I always heard about happening.
