The big glider was found by Dean Hickerson in December 1989 and was the first known diagonal spaceship other than the glider. Robert Wainwright discovered some small tagalongs for this spaceship, including one that can be used to string an arbitrarily large number of big gliders together and append certain glider tagalongs.
Two gliders can be temporarily seen at the front of the ship; these do not stay gliders but still move like them.
Some small tagalongs (in green); the block in the center tagalong can be removed or replaced with tagalong parts of Canada goose
or Orion 2
