747!?!? Try 707. All of Boeing's commercial airframe have been self-funded since before Airbus existed. There may be internal cross-subsidy from other defense projects (e.g. borrowing to develop A by using the federal funding of B as a loan guarantee) but no Boeing airframe you can buy today was started or funded as a DoD project.
