Other mistake: It shows an eagle-eye view of the downed plane with the pontoons floating separate from the plane; the plane starts to sink more and Agent Keen incorrectly says that one of the pontoons is taking on more water, even though they aren't attached to the plane and keeping it afloat anymore.

The Blacklist (2013)
1 other mistake in season 4
Starring: James Spader, Ryan Eggold, Diego Klattenhoff, Megan Boone
Continuity mistake: Right at the beginning of the episode a Cadillac Escalade gets stolen. The car is the newest model. The chase begins and the car is a new model right up to a scene when they crash into some other cars. That part was filmed with older model Cadillac. The damage is quite severe, but the chase continues again with the new model that has only one bit of damage - a mirror that has come apart.
Trivia: Red's trademark fedora was James Spader's idea.
Question: At the beginning of the final segment, the American Flag is flying upside down outside the beach lodge. Since it is pretty clear that Red would not being trying to elicit support/backup for the deeds that he and his female accomplice were about to undertake, what is the significance of this widely accepted distress signal?
