Air Carrier Maintenance Technician reported while disconnecting aircraft after push-back from the gate; another aircraft decided to taxi ahead of them causing a near miss with their aircraft and ground personnel.

Narrative

On Day 0; at approximately XA:00; a near-miss hazard occurred during pushback operations on the ramp involving a Boeing 717 aircraft. The 717 was positioned behind another aircraft that was still undergoing detachment by the push crew; who were actively tending to the tow bar and securing the area per standard procedures. Despite the visible ongoing activity and the brief wait required; the pilot of the trailing 717 decided to overtake the lead aircraft; maneuvering aggressively into the adjacent space without clearance or coordination.This unauthorized overtaking brought the 717 dangerously close to the push crew members; who were positioned near the lead aircraft's nose and equipment. The action created an immediate risk of collision with ground personnel and equipment; endangering union members on the ramp. No injuries occurred; but the incident highlights a recurring pattern of impatience during multi-aircraft operations; similar to the incident several months earlier a near-miss at Gate XX where Aircraft Y taxied past an active pushback detachment; disregarding the 'X' hold signal held by the belt loader driver. Additional parallels exist with prior reports taxiway incident near Gates XX/XX; and the tow bar/tractor accident; all stemming from rushed maneuvers that compromise ground safety.
