Continuity mistake: Six people jump out of a C-17 and Blackburn and Mandy are aboard the aircraft. The next shot shows the SEAL team in the air with parachutes. Then the scene goes to an air base in Incirlik, Turkey. Blackburn and Mandy are there. How did that airplane get from 200 miles inside Syria to a Turkish airbase before the SEAL team even hit the ground? (00:17:00)
Continuity mistake: In the first scene an armored vehicle is approaching with a small slit for the driver to see. In other scenes the driver has a much bigger window. (00:25:55)
Continuity mistake: Six people are lined up to jump out of a C-17. Two people jump out. In the next shot there are still six people lined up to jump. (00:16:20)
Never Out of the Fight - S2-E22
Continuity mistake: Bravo Team returns to Virginia Beach NAS, and Sonny's sunglasses are up on his baseball cap's visor as he sees Lisa and says, "Looking pretty damn good for a cake-eater." It cuts to Sonny and Lisa hugging, and Sonny is suddenly wearing his sunglasses; then in the next shot, the sunglasses are back up on his cap's visor. (00:25:05)
Continuity mistake: Clay usually carries the H&K416 with the 14.5" barrel with the addition of a Surefire suppressor and a variable optic scope, whereas the rest of the team caries the more compact 10.4" barrel with Surefire suppressors and Eotech optics. Sometimes Clay carries the M110 Sniper, all their gear changes up depending on mission. On this mission Clay is with the 14.5" with scope and later when he exits the sub tube he hands the sub crewman a 10.4" with Eoetch. They didn't switch weapons underwater. (00:00:45 - 00:06:00)
Rock Bottom - S2-E20
Continuity mistake: The team is somewhere in the Kashmir region and there's a few horses around them which appear to be wild. There is no farmhouse anywhere near them. The Seals end up commandeering the horses, and they're riding them. However, the horses have blankets and saddles on their backs. I'm pretty sure it's difficult to ride a wild horse, and they definitely didn't HAHO in on a mission with leather horse saddles and blankets. In addition, there was no farmhouse for them to find saddles to equip the horses. (00:27:15 - 00:28:30)
Continuity mistake: The Seals are on the edge of the Afghan, Iranian border, it's not raining, it's raining back at the base where the QRF Marines are on standby. When the QRF responds the attack helicopters decimate the enemy there's no clouds, fog or rain, however when the Osprey lands a few seconds later to pick up the Seals the weather is rainy, foggy and cloudy. The scenes were shot on different days. (00:27:30 - 00:34:30)
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.
