Based off the Canadair CL44 which is a Canadian Bristol Britannia and basically used like the Beluga and SGuppies for transporting RB211 engines for the Lockheed TriStar. This wasn’t logistical as this was slow and the RR Tyne engines weren’t suited for the task. It’s very small and dirty when you get up close to it, unfortunately my phone completely went and my iPad overheated so I couldn’t get any photos of it last year. It’s still there though! Built by the same mastermind behind the genius Super Guppy, which I’ve seen #1 and #2 which are amazing machines too!
