Some articles I found suggest that a trip was 8 hours to get there and back. Another mentioned being in the sub for 12 hours. I'm guessing it's a 4 hour trip each way and then they spend a number of hours checking the wreckage. The wreckage site is around 370 miles from Newfoundland, Canada. Seems like the rescue effort could be unfolding over days.
