Can you get sucked out of a hole in an aircraft?
Yes, it's real. Here's the official accident report on BA5390, which says:


  The commander had been partially sucked out of his windscreen aperture


And:


  The two men tried to pull the commander back within the aircraft [but]
  the effect of the slipstream frustrated their efforts


There's also Aloha 243 where one cabin crew member was ejected, although that was a really extreme case.
