We first examine the first branch of the easement criteria, the open,
  visible, and adverse requirements for a prescriptive easement.  We have
  no trouble concluding that the County's use of the glide paths was open
  and visible.  Aircraft regularly passing overhead during their landings
  and takeoffs are hard to miss.  And defendants have offered no evidence
  that any Stealth fighters operated on runway 11/29 or that any of the
  aircraft used the infamous Romulan cloaking device.

     793 F. Supp. 1195, 1207-8 (S.D.N.Y.) 1992.  Opinion by U.S.
     District Judge Gerard L. Goettel.
