Alien Spacecraft Invade Arizona Town

On my way home from the gas (petrol?) station I couldn't take my eyes off of the sky.  In every direction I saw space alien aircraft, disguised as clouds, enveloping our town.  (I think they were  snow  summer birds from Venus.  I understand it's pretty hot there.)  I put a second view in as an extra.
