Data says this to Riker, which made me think Data might be wrong (wrong about correcting him, not that it wasn't true)
RIKER: Their Bridge. If this thing works, be sure to record everything.
(The picture gets cleaned up)
RIKER: You were right. Somebody blew the hatch. They were all sucked out into space.
DATA: Correction, sir, that's blown out
RIKER: Thank you, Data.
DATA: A common mistake, sir,
Now the thing is both are equally descriptive and BOTH completely right:
- Blown out: an object pushed from a high pressure area to a low pressure area
- Sucked out: an object pulled out from a high pressure area to a low pressure area
Since both are technically correct, the question here is why is Data bothering to correct him? It's not clear why he says this to Riker.
