For those who don't speak Spanish, some of the key points they make are:
Helidosa has a history of accidents and has been constantly criticised for poor maintenance and for pilots not getting scheduled rest. People have died in previous helicopter accidents. Supposedly the day before the accident the pilot was heard saying that there's going to be an accident here very soon.
They question how the company grew so rapidly and say this all happened after Danilo came to power.
They question how the authorities who should have investigated bad practices did not, and point to the fact that Gonzalo Castillo was president of the company and the presidential candidate
The pilot reported that the plane had a problem and was told that this had been corrected. His sister is also saying that pilots were expected to work more than 12 hours without a break. They show a list of all the flights that the pilot / co-pilot had been required to fly in the last few days and say this amount of work is "inhuman"
At timeline 14.00 they show the plane attempting to land at Las Americas. They say that according to pilots they have spoken to, the ailerons were jammed and it appears that the plane clipped the runway and caught fire on impact. It's also apparent that the plane was still in one piece coming in to land so it seems that everyone died when it hit the runway.
US air accident investigators are working alongside Dominican investigators to establish the cause of the crash.
The key point that they repeatedly make is that the authorities who should have shut this firm down didn't do so because Gonzalo Castillo was the president. People who campaigned for his election were employed by the authorities which should have regulated his airline.
The fact that the cabin crew member who died was daughter of someone so influential in the current government, just 18 and doing her dream job, means things are looking a little more ugly for Helidosa.
