50 year old Gazelle!
Used to fly under theh 59th St. Bridge to get in to 60th St. with certain winds in the old days of NYC ops.
Perfectly acceptable, nothing to underestimate with respect to ropes or cables hanging underneath the bridge.
Is what it was.
50 years from now we'll be so restricted by the FAA it'll take an act of the good Lord just to start the freaking thing.
