Many who wonder about the Roswell crash wonder why ET did not retrieve its own craft and crew. How can we fathom that they left their own on the desert floor? This is a question that has an answer, though we have no obligation to provide one. This is because the Alien Intent can never be fully discerned with any certainty. But we can try.
There are seven possible scenarios- one of which may well have played out in July of 1947 over the skies of Chaves and Lincoln Counties:
1) Perhaps the craft that crashed did not have a "companion craft" or "mothership" in the nearby cosmos to be able to arrive in time to Earth to make a recovery. Man has never sent multiple spaceships at the same time to the same destination.
2) If such a ship were in the area, perhaps the retrieval of all the strewn debris, craft components and corpses would have too difficult to accomplish (and cover up) in time to remain undetected. ET did not wish to risk further exposure -or perhaps even confrontation- with Man. It took us many days and many people to retrieve everything. And still it was not done effectively. The retrieval was seen by those who should not have seen, with some of the material being taken by them.
3) Maybe ET did try a crash retrieval, but simply failed to locate the craft and arrive in time. The debris and bodies may have already been discovered by us by then. Sightings of UFOs in the region spiked in the days immediately following the crash. Was ET still looking for its fallen?
4) ET may well have had a concern about the safety of retrieval. Whatever caused the crash to occur in that area at that time (such as a missile or triangulated radar beams) could cause a retrieval craft to come in harm's way too. The risk assessed, they elected not to initiate a recovery operation.
5) Warring factions of visitors caused one to ram to the ground. The aerial battle engaged- priority and concern was for survival, not retrieval.
6) Just as it was the first time that we did not know immediately quite how to handle the situation, it was the first earthly crash that ET had experienced. They may well have had similar hesitancy or disagreement about dealing with the event. This delay may have prevented a timely retrieval.
7) ET did not want to retrieve. They may have in some way desired to "seed" or "plant" themselves and their technology with Man at that point in history. The crash would give Man concrete knowledge that he is not alone in the Universe. They may have hoped that this would curtail further development of nuclear armament, promoting peace and openness. ET can be wrong.
Man must assign cause or motive to the unexplained. It is our compulsion...for man learns nothing except by going from the known to the unknown. But why they came here, why they crashed and failed to retrieve- are things perhaps forever unknowable.
