The single runway (10/28) at Mataveri International Airport (IPC/SCIP) on Rapa Nui1 has (at least according to Google Maps) a few paved protuberances emanating from partway down its northern edge which serve no obvious purpose:
I wondered if at least some of them might be the old turnaround pads from before the runway was lengthened in the early 1980s, but:
- if that were the case, one would not expect them to still exist in what at least appears to be good condition a third of a century later, and
- they look far too small to be turnaround pads emeritus - compare, for instance, the turnaround pad at the approach end of runway 28:
Does anyone know what these appendages are, and what purpose they serve?
EDIT: As @MikeSowsun points out, the runway would not only have been shorter then, but narrower as well (not having needed to serve widebody jets or distressed spacecraft), meaning that the turnaround pads themselves could be smaller, and that they'd have been at least partly paved over when the runway was widened (leaving only the outboardmost portions visible); this still doesn't address the issue of "how come they're still visible a third of a century after being abandoned", though.
