The NASA is utilizing a modified U-2 spy plane to study a lesser understood meteorological phenomenon. This plane, called ER-2, has been equipped with scientific research instruments. It is being used to investigate storms generated by wildfires.

These storms, known as pyrocumulonimbus, are massive electrical storms produced by the heat of wildfires. They can include lightning, strong winds, and in some cases, fire tornadoes. Further details about this research and the ER-2 plane's mission are available from the source, including information on the plane's modifications and its role in studying these storms.
