Special Paint on the Hood of the World War II Jeep Could Detect Mustard Gas

It is odd that the article doesn't delve into that point more. In the early stages of the war, actually from mid-1938 onwards, British aircraft and vehicles had 'gas detector' panels which were squares paper soaked in the detection paint and taped-on. It was usually yellowish with one on the wing or the fuselage-spine of aircraft:

Those fell out of use from late 1940 due to the low risk of gas attack and production ended in 1943. Just as the USA was starting production of its M5 paint!
As war seemed more and more likely from the mid-1930's onward, a lot was talked about the possible merger of chemical warfare and new airplane technology.
A particularly haunting line the author cites from a contemporary historian talked about how “a few dozen bombers can spread enough gas to push over all of Paris a tsunami of mustard gas 100 feet high and 50 miles wide”.
Probably not true, but interesting how they merged threats old and new.
He also predicted the international post service would take over the world and enforce universal basic English as the global standard language, so... some good ones, some bad.
Still, the sub warfare bit was very prescient.
> ...agents like mustard gas, which have a characteristic odor, tend to dull a victim’s sense of smell “after only a few breaths so that the smell can no longer be distinguished.” In addition, the implementing body of the Chemical Weapons Convention states, respiratory damage can occur in the presence of even tiny, unsmellable concentrations of the agent.

Sulfur mustard damages cells within minutes of contact; however, the onset of pain and other health effects is delayed until hours after exposure.
