Mexicana Flight 704 Wikipedia
On June 4, 1969, Mexicana Flight 704, a Boeing 727-64 airliner registered XA-SEL, crashed near Salinas Victoria, some 20 miles north of the city of Monterrey. All 79 people on board were killed, including Mexican tennis star Rafael Osuna and politician Carlos A. Madrazo. The aircraft was approaching Del Norte International Airport near Monterrey. It had made a continuous descent in the last 5 minutes before impact. The pilot turned left instead of right once the aircraft had passed over the Monterrey VOR, apparently not knowing his exact position at the time. The aircraft collided with Cerro del Fraile upon impact and broke up.
The crash of Flight 704 was the deadliest aviation accident on Mexican soil until Mexicana Flight 940, another Boeing 727, crashed on March 31, 1986, killing all 167. It remains Mexico's second-deadliest aircraft accident to date, behind Flight 940.
