The Strength of the Wolf - S3-E4
Audio problem: One of the team members shoots a sentry on board a ship off a ladder attached to the deck hanging off the side of the ships hull. He shoots an unsurpassed Glock and the shot sounds suppressed. A muzzle flash can be seen too, another indicator it's unsuppressed. Their element of surprise would have been totally eliminated had this really happened. They've used suppressors before on their sidearms - doesn't make sense why they wouldn't now. (00:31:00)
Answer: Yes. They would have to land 3-4 times for refuelling. The plane could fly with the wheels down, but the additional drag slows the plane and increases fuel consumption.
