As Lockheed, with its P-38 design, failed to reach the long-range specifications, the Burnelli company modified it with much more room for fuel: UB-38.
Trans-Pacific ability!

The UB-38 (then improved UB-38A) was the "real" part, but Ing. Burnelli then said this plane coulda/woulda/shoulda have radial engines like his UB-14B: this led to the UB-38B...

My son Jacky disapproved this design UB-38B and required the tail to be removed, and the colour to be changed (shoulda!): UB-38J

Engineer Jacky, 4 years old, required less realistic colours, and I added a canard tailplane for balance...

As the foreplane denied the "flying wing" name on the UB-38K, we coulda/woulda/shoulda add fins for better control: UB-38L

Cooperation with my little son goes on, do you adults have other improvement ideas?

To take off with trans-Pacific fuel, 3 engines might have been necessary:

With a very long runway and reduced drag, one engine might have been enough at last...

With a bigger engine and even reduced drag, this gave the UB-38MD (Minimum Drag):

A derivative of the former, more balanced when the tanks are empty: UB-38ME

UB-38MF: reduced drag did not mean two engines were forbidden (to have a free nose)

Wrong! A Lightning cannot be single engined! A Zwilling may cure the problem, even in the flying wing family:
