Planes have mechanical problems, that is a fact..they don’t disappear off the face of the earth

Sometimes they do. Lots of examples where they were found years later. Sometimes pilots fly perfectly good airplanes into the water or earth. A 777 maybe big but the Pacific is a lot of real estate to hide in.

Just heard on CNN how radar showed that the plane went as low as 12,000 feet..but then went back up to normal altitude, shows only a human could have done that
