Did you get a flu shot this year? How about last year? In a world of next-day delivery and instant downloads, making the yearly pilgrimage to the doctor or the minute clinic feels like an outdated concept. Even if you get your shots free at the office, it’s still a pain to have to get vaccinated every year.
Unfortunately, there’s really no other way to deal with the annual threat of influenza. There’s no single vaccine for the flu because there are multiple strains that are always mutating. Unlike other viruses with one-and-done vaccinations, influenza is a moving target. Developing, producing, and distributing millions of vaccines every year is a massive operation that never stops, or even slows down a little bit. It’s basically Santa Claus territory — if Santa Claus delivered us all from mass epidemics.
The numbers are staggering. For the 2018-19 season, as in last year, there were 169.1 million doses distributed in the United States, up from 155.3 million doses the year before. How do they do it? We’re gonna roll up our sleeves and take a stab at it.

Imagine it’s 1943, and you have to transport 1,000 P-47 fighter planes from your factory in the United States to the front lines in Europe, roughly 5,000 miles over the open ocean. Flying them isn’t an option, the P-47 has a maximum range of only 1,800 miles, and the technology for air-to-air refueling of fighter planes is still a few years off. The Essex class aircraft carriers in use at this time could carry P-47s in a pinch, but the plane isn’t designed for carrier use and realistically you wouldn’t be able to fit many on anyway. So what does that leave?
It turns out, the easiest way is to simply ship them as freight. But you can’t exactly wrap a fighter plane up in brown paper and stick a stamp on it; the planes would need to be specially prepared and packed for their journey across the Atlantic. To get the P-47 inside of a reasonably shaped shipping crate, the wings, propeller, and tail had to come off and be put into a separate crate. But as any reader of Hackaday knows, getting something apart is rarely the problem, it’s getting the thing back together that’s usually the tricky part.
So begins the 1943 film “Uncrating and Assembly of the P-47 Thunderbolt Airplane“ which has been digitally restored and uploaded to YouTube by [Zeno’s Warbirds]. In this fascinating 40 minute video produced by the “Army Air Forces School of Applied Tactics”, the viewer is shown how the two crates containing the P-47 are to be unpacked and assembled into a ready-to-fly airplane with nothing more than manpower and standard mechanic’s tools. No cranes, no welders, not even a hanger: just a well-designed aircraft and wartime ingenuity.

Gen. Robert H. Barrow, USMC, once said that “Amateurs talk about tactics, but professionals study logistics.” That’s true in many enterprises, but in warfare, the side that neglects logistics is likely to be the loser. Keeping soldiers fed, clothed, and armed is the very essence of effectively prosecuting a war, and the long logistical chain from rear supply depots to forward action is what makes that possible.
Armies have had millennia to optimize logistics, and they have always maximized use of new technologies to position supplies where they’re needed. Strong backs of men and beasts sufficed for centuries, supplemented by trains in the 19th century and supplanted by motor vehicles in the 20th. Later, aircraft made an incalculable impact on supply chains, allowing rapid mobilization of supplies and supporting the industrial scale death and destruction of the 20th-century’s wars.
