On January 1st, 2012, the day after New Year the unthinkable happen three plane crashes on Canterlot Steppest Intl Airport. 39 passengers and crew died.

Aircraft
The aircraft that involved in the crash is the 22 years old Lockheed Tristar L-1011 (Everfree Airlines flight 211), 10 years old, Boeing 777-300ER (Air Luna flight 12), and 12 years old Airbus A320 (Equestrian Airlines flight 920)

Accident
Air Luna flight 12 is arriving at the airport. the flight was a scheduled domestic flight from Hope Hollow to Canterlot with 132 passengers and crew on-board. ATC cleared Flight 12 to land. On the airport, Equestrian Airlines flight 920 is preparing for takeoff. The flight was a routine International flight from Canterlot, Equestria to Horsolulu, Hawila with 130 passengers and crew on-board. ATC cleared Equestrian Airlines Flight 920 to takeoff runway 09L. But ATC saw Air Luna flight 12 landing at 27R. The ATC immediately instruct Air Luna flight 12 to abord landing but, no answer then they instruct Equestrian Airlines Flight 920 but they already reaching V1 (Decision Speed) and taking off. Now pilot on flight 920 know the problem and deviant to the left so they don't collide but, because Air Luna flight 12's distance is too close to Equestrian Airlines flight 920, the plane engines on Air Luna flight 12 struck an Equestrian Airlines flight 920's stabilizer and make Equestrian Airlines flight 920 out of control. on the runway 36R, Everfree Airlines flight 211 is waiting for passing clearance. Flight 211 is a routine flight from Neigh York to Canterlot with 210 passengers and crew on-board. Flight 211 is waiting in the taxiway when all of sudden Equestrian Airlines flight 920 is coming straight to Flight 211, then the pilot of Everfree flight 211 turn the plane to the right to avoid the collision but eventually Equestrian Airlines Flight 920's left-wing slams into Everfree Airlines Flight 211's fuselage and Equestrian Airlines crash on the taxiway. In the end, 35 people are killed (all on the Equestrian Airlines flight 920) and 130 people are injured (17 on Everfree Airlines flight 211, 21 on Air Luna flight 12, and 92 on Equestrian Airlines flight 920)

Cause
Equestria National Transportation Safety investigate the accident and found out that the pilot on Air Luna flight 12 make a fatal mistake, instead land at runway 0-9R they decided to land at runway 2-7R the runway that not told by the ATC and the runway that Equestrian Airlines flight 920 was prepared for takeoff (opposite of runway 2-7R (0-9L)) to cut the time process. So the crash is caused by a pure pilot error
