Adam W's 100wc - week 5...

Long in the future there lived a man called jack, who was always in a hot air balloon or a plane or anything that flies. As he looked back he screamed, on the window an ugly monster splattered against the window with saliva down the monsters face.He started to slip of the window, jack looked back to the front he didn’t want to get out.but in came a load of people he was squished so decided to walk out the plane the monster had vanished it was nowhere to be seen.Had it fell from mars?, how did it vanish?, or is it still there?
