I write this post to ask you your opinion about a couple of questions related with an helicopter crash happened in 1989, in the sea, a few miles of the coastline of Roquetas de Mar town, province of Almeria (Spain). I am analyzing this misterious crash in my spare time. Many thanks in advance for your opinions.
On December 15th, 1989, 7:00pm, a helicopter of the Spanish Customs Surveillance, model Messerschmitt-Bölkow-Blohm BO-105 CB, with two helicopter pilots, departed from the airport of Almeria (Spain) with destination to the area of Melilla (Spain).
On December 16th, 00:40am, the members of the control tower of the airport inform the helicopter is missing (the autonomy of this helicopter was 4 hours)
On December 16th, 07:00am (about 12 hours after the crash) a fishing boat finds two miles far from the coastline of Cerrillos Beach (Roquetas de Mar, Almería, Spain) the body of one of the helicopter pilots floating with the cross arms. The distance from the airport is about 10 miles, which is why it is supposed the accident happened about 20 minutes after the departure.
From the analysis of the body (autopsy) the investigators concluded that the helicopter did not explode in the air. Two main hypothesis were managed. The first one was that a distraction of the pilot could have caused the crash, while the second one was a possible mechanical failure, perhaps a failure in the altimeter system. These service
During two weeks several ships search this area looking for the
fuselage and the body of the other pilot, but they were not found. Today, it is still a mystery was happened, and where is the fuselage.
I am analyzing the possibility that the fuselage of the helicopter could still be located in the bottom of the sea. Taking into account that this coast is micro-tidal (it is not influenced by tides, but only by waves in the surface) I would be expeted the helicopter fuselage is still in the same place it crashed in 1989. Nevertheless, this
helicopter model had inflatable floats, which is why I need to answer to several questions before to conclude the fuselage is still in this area. If possible, give me your opinion using percentages of probability to each question (of course, your comments are also welcome).
Q1) Taking into account that one of the cadaver of one of the pilots was found few hours after the accident, do you think he jumped before the crash (the other alternative would be he had been able to get out the helicopter after the crash)?
Q2) If the crash happened suddently, do you think the pilots could have activated the inflatable floats before sinking?.
Q3) If the crash happened because a mechanical failure, and the pilots had a few seconds before, do you think they had time to activate the inflatable floats before the crash/sinking instead (in addition to make efforts to recover the helicopter or jump from it)? [Probability 0%-100%]
Q4) Having in mind that the pilots of the Spanish Customs Surveillance fly at low altitude, and that floats require some seconds to be inflated, and supposing they activated the inflation process a few seconds before the crash, do you think the inflatable floats were totally inflated after the crash (i.e. a crash do not affect to the inflation process)?
Q5) In case the floats were totally or partially inflated, do you think the descending vertical force exerted by the crashed helicopter full of water would be greater than the ascending vertical force exerted by the floats (i.e. the helicopter would directly go to the bottom of sea)?
Q6) In case the inflation mechanism of floats were not activated, do you think it is possible that the helicopter could remain like an air camera between the top and the bottom of the sea during a certain time (hours/days)?
Q7) In case the inflation mechanism of floats were activated, and the floats were totally or partially inflated, do you think it is possible that the helicopter could remain like an air camera between the top and the bottom of the sea during a certain time (hours/days)?
