Incident: China Eastern A333 at Shanghai on Oct 11th 2016, runway incursion forces departure to rotate early and climb over A333

A China Eastern Airbus A330-300, registration B-6506 performing flight MU-5106 from Beijing to Shanghai Hongqiao (China), had landed on Hongqiao's runway 36R and was taxiing to the terminal needing to cross runway 36L. The aircraft, that had been previously cleared to cross runway 36L, was instructed to stop and hold short of runway 36L but did not react to the stop instruction.
A China Eastern Airbus A320-200, registration B-2337 performing flight MU-5643 from Shanghai Hongqiao to Tianjin (China), was accelerating for takeoff from Hongqiao's runway 36L when at about 110 KIAS the crew spotted the A330-300 crossing the runway edge and assessed that they would not be able to stop in time to avoid a collision, however, they would be able to outclimb the A330. The crew firewalled the engines, continued their takeoff run, rotated the aircraft at about 130 KIAS and managed to climb the A320 over the A330. The A320 continued to Tianjin for a safe landing about 100 minutes later.
China's Civil Aviation Authority CAAC reported that the A320 was in their takeoff run when the A330 crossing the runway appeared in front of them. The A320 captain assessed that it was safer to continue, the rest of the flight was without further incident. An investigation into the serious incident has been opened.
On Oct 12th 2016 the CAAC reported that preliminary investigation results suggest the serious incident was caused by a tower controller's misdirected instruction.
On Oct 15th 2016 the CAAC reported that the separation between the aircraft reduced to 19 meters vertical and 13 meters horizontal (wingtip to wingtip) while the A320 climbed over the vertical stabilizer of the A333. Screenshots off and the reconstruction video below.
According to the reconstruction video the A320 lined up runway 36L at taxiway H7. The A333 was taxiing on taxiway H3 and crossed the right runway edge when the A320 was just short of taxiway H4 about 1600 meters/5250 feet into the takeoff run and about 770 meters/2530 feet short of taxiway H3. The A320 became airborne abeam taxiway C2 about 2100 meters/6890 feet into the takeoff run and about 300 meters/1000 feet short of taxiway H3, and crossed taxiway H3 19 meters/62 feet above the vertical tail of the A332.
Chinese media are reporting (no official statement to the sequence of events released by the CAAC so far) that during the presentation of the video it was said, that the A330 had been cleared to cross runway 36L at H3 about 36 seconds prior to the A320 receiving takeoff clearance, by which time the controller had forgotten about the earlier crossing clearance, the A320 crew had not yet been on frequency and therefore had not heard the crossing clearance. After the A330 crossed the hold short line tower called the A330 three times to stop, however, the crew did not listen. The crew also did not check whether the runway was clear prior to cross the hold short line blindly trusting in the ATC instructions. In addition, the cockpit voice recorder of the A330 was not secured and was found overwritten. Takeoff performance computation shows, that even from V1=146 KIAS (with Vr=147 KIAS, V2=151 KIAS) the A320 could have stopped within 475 meters (thus permitting the aircraft to stop more than 200 meters short of H3 had takeoff been rejected abeam H4 at about 110 KIAS), however, the captain had no real time measurements of distances remaining available. The CAAC are going to decide about punishments on Oct 17th.
