A Sci -Fi one Called "colony ship arrival", could be crash landing, normal landing, a ship terraforming the earth for aliens to live on or a seed ship that lands and then robots start to build structures and fertilise embryos literally building a colony from the ground up!
Or an Event from history, Battle of hastings 1066, viking raid on Lindisfarne island or even Roswell and the baloon or ship depending on your conspiracy theory!
