CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR SAID HE WAS MANNING LCL CTL AND GND CTL. HE HAD CLRED THE PIPER ARROW TO TAXI TO RWY 28 VIA TXWYS H; M; AND L. HE CLRED THE JETSTREAM FOR TKOF ON RWY 28. AS HE TURNED TO WATCH THE TKOF HE SAW THE ARROW TAXI ON TO RWY 28 AT TXWY G; AND MAKE A R TURN TO TAXI E ON RWY 28. HE DIDN'T TELL THE PIPER TO GET OFF THE RWY FOR GOOD REASONS AND HE DID NOT TELL THE JETSTREAM TO ABORT NOT KNOWING THE STOPPING CAPABILITY OF THE JETSTREAM. HE TOLD THE DEPARTING JETSTREAM THERE WAS AN AIRPLANE ON HIS RWY WHEREUPON THE JETSTREAM ABORTED AND THE PIPER ARROW HEARING THIS REALIZED IT WAS HIM AND MADE AN IMMEDIATE R TURN INTO THE GRASS. THOUGH THERE ARE OBSTACLES AND DITCHES IN THE AREA THERE WAS NO DAMAGE TO THE PIPER ARROW. THE JETSTREAM TAXIED OFF THE RWY AT TXWY C AND WENT BACK TO RWY 28 FOR AN UNEVENTFUL TKOF. THE LCL ARPT MGMNT TALKED TO THE PIPER ARROW PLT AND PROBABLY RPTED THE EVENT TO FSDO.
