Before The Storm Season 2: MIssion 01
This will bring the total up to 78 episodes by the time Season 3 ends which will effectively make this show have had more screen time than the original series. But, by extension, this was already achieved with it being renewed for a second season, but the point still stands.
Also, check out Philip Wray's Compositing Reel. Really talented Visual Artist
Safe to say we will be seeing the adventures of International Rescue for some time to come.
