Why tomato juice?

Yesterday I came across this story about why people drink tomato juice on planes but couldn’t read the German. Tyler Cowen summarizes:

During a flight, everything tastes quite a bit weaker, as if you had a cold. You might think die deutschen would turn to Sichuan Chili Chicken, but no…Tomatensaft!

Growing up I would always drink ginger ale on planes. I rarely drank it other times and to this day I associate ginger ale with flying. I assumed this was a random preference, but perhaps not.
