I'm sure someone in the 90's was using rockets without wires, the exhaust from the rocket made the trail. I cannot source it.

These guys charging cars shows they are not really serious, but a lot of forest fires are lightning, it's a worthy thing to control if possible.

Apollo 12, in November or December 1969, was struck by lightning due to the exhaust.

“A patented new rocket design eschews the copper wire and chemically creates the lightning path. The rocket fuel is doped with small amounts of salt. Sodium chloride, calcium chloride, or cesium chloride is pulled through the motor, heated, and broken into charged ion components spewed out in the exhaust. The positively charged Cs, Ca, or Na atoms cool and bond with water molecules in the air, forming saltwater droplets. These droplets are far more electrically conductive than freshwater droplets, leaving a high-conductivity trail in the rocket’s wake.”

Patent link (https://patentimages.storage.googleapis.com/af/69/e2/0303f86...) says it was filed in 2001, however, not the ‘90s.
