Fun fact, the development of the B-29 bomber was more expensive than the entire Manhattan Project. Its use in the Pacific Theater during WWII led to it being used to drop the atomic bombs on Japan, but after the war, the rise of jet planes (as opposed to those with propellers, like the B-29, John here, or the DC-3, Mary) began the slow process of it being phased out, its service in the Korean War notwithstanding. Similarly, Douglas MacArthur had seen his glory days come to pass, having been relieved of his command in Korea a couple of years earlier for insubordination. So the backdrop to this lighthearted short from the legendary Tex Avery were these shifts in the military, and it perhaps also resonated with veterans competing in a younger workforce.
There are lots of amusing gags to be found in this pair of bombers giving birth to a baby jet, who then zooms in and out of the house while his mother holds up food or new diapers for him to pick up while whizzing by. The smog being removed from Los Angeles was a cute reference to a problem that was just then on the rise in the city, and who can resist the Leaning Tower of Pisa being tilted the other way, or the Statue of Liberty's undergarments being revealed? Naughtiest of all was the mass production reference at the end, and the blush on the mother plane's face was priceless.
