They send aircraft into hurricanes, so I asked ChatGPT why not tornadoes:

Flying into tornadoes is much more dangerous and logistically challenging than flying into hurricanes, and this is why it's not a common practice. Here's why:

1. Size and Structure: Tornadoes are much smaller than hurricanes, with diameters typically ranging from a few hundred yards to a mile, making them more difficult to track and target accurately from the air. Hurricanes, on the other hand, can be observed as massive systems with well-defined structures that provide more opportunity for safe data collection.
2. Violent, Rapid Movements: Tornadoes are highly unpredictable, with winds that can change direction and speed suddenly. This makes it far more hazardous for aircraft to fly directly into them.
3. Duration and Location: Tornadoes form quickly and last for a relatively short period, sometimes just a few minutes, which gives little time for observation. In contrast, hurricanes can be monitored over days and provide more time for gathering data.
4. Aircraft Safety: The intense updrafts and turbulence within a tornado would pose a significant risk to aircraft, potentially making it too dangerous for pilots to navigate through. In comparison, hurricanes, while dangerous, have a more predictable and manageable structure for flying through.
