Aircraft
While climbing out of FL387 after departure a very loud POP was heard and soon shortly after smoke was visible coming up from under the co-pilots seat on the bulk head side of the aircraft. An acrid smell was observed; climb of the aircraft was stopped and transmission to ATC was made in regards of getting lower and deviating to a nearby airport. Smoke was only visible for a few seconds and dissipated very quickly. An emergency descent was performed; fire extinguisher was removed from the holder in case it was needed. No adverse electrical conditions were observed and no circuit breakers were open. Normal approach and landing were made. Emergency was not declared.
A BE-400XP developed cockpit smoke originating from the First Officer's side wall so the climb was stopped and a descent to landing at a nearby airport completed. The smoke dissipated and no popped circuit breakers were found.
