  Here we extrapolate the idea of launching SpaceX's Starlink satellites and
study the possibility of building planetary megastructures (either designed as
solid objects or as a web of satellites) by Type-I civilizations and the
consequent detection of their techno-signatures. We have shown that the
instruments of The Very Large Telescope Interferometer (VLTI) can potentially
observe emission pattern of the huge constructions. Efficiency of the spectral
variability method has been emphasized and the role of the FAST telescope was
discussed.
