The stolen Kelsan KS bomber has been intercepted and destroyed before it could launch it's payload of biological weapon loaded missiles at Dino-Land. If the attack had taken place it could have killed millions due to the incredibly toxic level of the biological weapon (thought to be stolen military grade Utrek material).
Zone renegrades had stolen the Kelsan and were planning to launch the attack. The Clones worked with the Dinos to avert a catastrophe which could have sent the Local Group into full scale war.
