What appears to be one of three survivors, according to state media, shuttled quickly to an ambulance. The jetliner, with more than 100 on board, slamming into a field of crops. In Havana. Our affiliate WPLG is on the scene. Look at the crowd. These are Cubans trying to figure out exactly what happened. Many of them say they arrived here when they saw a plume of smoke. Reporter: Difficult to recognize the Boeing 737, as water was poured onto the wreckage, just a couple of miles from the airport where the jet took off from. It would suggest something catastrophic happened either on the takeoff roll or right as the aircraft was lifting into the air. Perhaps an engine failure. Perhaps a controllability issue. Reporter: The jet, heading to the other end of the island, was leased from a Mexican company. State-owned cuban airlines had grounded many of its own aircraft due to maintenance issues. The 737 that crashed is an older model and had many previous owners.
