LEGO builder Jack Carleson is back with yet another model that shows why he goes by the screen name “Big Planes.” Following up on his incredible minifigure-scale Air Force One, Jack brings us a huge model of the Convair B-36D “Peacemaker” from the early cold war era.

Entering service in 1949 with a profile that fits right between the B-29 that preceded it and the B-52 that replaced it (which is still in service), the B-36 is nonetheless distinct with its six push-prop engines augmented with four jet engine nacelles. Jack’s model is massive with a wingspan of 6 feet. That’s all the more impressive when you look at how rigid the self-supporting wings are, which is an amazing feat of LEGO engineering.

The LEGO B-36 is equipped with a full crew of 15.

While the interior is naturally a bit cramped, it does have a full cockpit and bomb bay.
