Definition of blue jet
- Wescott and Sentman discovered that sprites are salmon-colored, and as they flew with Tobolski over the Arkansas storm that summer, they discovered that sprites were not alone above the clouds: fountains of blue light emerged directly from the clouds as well. These they named blue jets.

- Blue jets, by far the rarest member of the menagerie, shoot up from cloudtops at speeds of more than 60 miles a second to heights of 30 miles.
