With its folding wing configuration and matching cockpit module, the Sentinel-class landing craft was based on the Lambda-class shuttle, both shuttles having seen design origins in the Theta-class shuttle (Wikia)
Is there a reliable way to tell whether a shuttle is Lambda or Sentinel class visually? (e.g. in a film/cartoon scene)? Such as different shapes, detailing, colors, etc...?
I will accept size at last resort since in some visual scenes you can see the shuttle next to another known-size craft or object; but I strongly prefer other methods that would work even if the shuttle is the only object in visible frame of reference.
