The "helicopter" image is the result of carved stone being re-used over time. The initial carving was made during the reign of Seti I and translates to "He who repulses the nine [enemies of Egypt]". This carving was later filled in with plaster and re-carved during the reign of Ramesses II with the title "He who protects Egypt and overthrows the foreign countries". Over time, the plaster has eroded away, leaving both inscriptions partially visible and creating a palimpsest-like effect of overlapping hieroglyphs.
In paleocontact hypothesis circles the hieroglyphics have been interpreted as an out-of-place artifact depicting a helicopter as well as other examples of modern technology. This claim is dismissed by Egyptologists who highlight this pareidolia is partly based on widely distributed retouched images that removed key details from the actual carvings.
