Flew in an 8-9 passenger Cessna 208B on Vieques Air Link from smaller Isla Grande airport (SIG) in San Juan to the island of Vieques (VQS) off the east coast (20min).
No security, no metal detector, no ID check (they just asked my name and checked their list). Well a dog did sniff the carry on bags before boarding.
Flight hugged the coastline and never went over 1800 feet! I noticed it felt lower than a basic skydive do I peeked at the pilot’s instrument panel.
Main island in PR has a mountainous centre and some swampy areas inland from the scenic coast.
