Apparently there is a short video of the accident from cameras next to the t4 or the satellite pointing to the RWY. Itīs been viewed by the authorities and some media.
It seems that the MD took off "short of power", stalled, right wing made contact with the rwy en then..well we know what happened.
Doubts are arising about any engine failure because here seem to be no explosion in any engine. The aircraft apparently exploded when it crashed agains the rwy and the adjacent field.
A pilot landing (returning from Guayaquil..IB pilot? )saw that the MD was taking a lot of the rwy to depart, and he thought that they were not gonna make it.
He has been called by the police to tell them what he saw.
