Did you start at 4:38 this morning?

The outright cancellation of the Boeing contract on 11 December 1947 was staved off by a plea from its president William McPherson Allen,[11] and in January 1948 Boeing was instructed to thoroughly explore recent technological innovations, including aerial refueling and the flying wing.

Noting stability and control problems Northrop was experiencing with their YB-35 and YB-49 flying wing bombers, Boeing insisted on a conventional aircraft, and in April 1948 presented a US$30 million (1948 dollars) proposal for design, construction, and testing of two Model 464-35 prototypes.

Oh dear, my maths is terrible. I of course meant 2:38 this morning....

I can see numerous tabs being open that day

In May 1948 the AMC asked Boeing to incorporate the previously discarded, but now more fuel-efficient, jet engine into the design. This resulted in Boeing developing yet another revision — in July 1948, Model 464-40 substituted Westinghouse J40 turbojets for the turboprops.[12] Nevertheless, on 21 October 1948, Boeing was told to create an entirely new aircraft using Pratt & Whitney J57 turbojets.

On 25 October, Boeing engineers produced a proposal and a hand-carved model of 464-49.[13] The new design built upon the basic layout of the B-47 Stratojet with 35° swept wings, eight engines paired in four underwing pods, and bicycle landing gear with wingtip outrigger wheels.

A notable feature of the landing gear was the ability to rotate all wheels up to 20° off the centerline to increase safety during crosswind landings.[14] The aircraft was projected to exceed all design specifications.[3] Although the full-size mock-up inspection in April 1949 was generally favorable, range again became a concern since the J40s and the early model J57s had excessive fuel consumption.

Despite talk of another revision of specifications or even a full out design competition among aircraft manufacturers, General LeMay, now in charge of Strategic Air Command, insisted that performance should not be compromised due to delays in engine development.[15] In a final attempt to increase the range, Boeing created the larger 464-67, stating that once in production, the range could be further increased in subsequent modifications.
