gusts peaked at , uprooting trees. However, damage outside of trees was primarily insignificant. In Bonaire, piers were destroyed, and the island's coastal boulevard was damaged. Beach facilities at Curaçao's Piscadera and Vaersen Bays suffered considerable damage. Quays along the harbor entrance were also damaged. Snowcloud Five On September 26, the hurricane hunter P2V-3W Neptune aircraft Snowcloud Five, led by U.S. Navy Lieutenant Commander Grover B. Windham, was sent from Guantánamo Bay to investigate Janet, which was at the time a Category 4 hurricane south of Jamaica. Upon penetration of the hurricane's eyewall at an altitude of , a final transmission was received from the reconnaissance flight before it presumably crashed in the Caribbean Sea. All 11 people on board, including nine crew members and two journalists, were killed. Following the loss of the plane, an extensive search and rescue operation took place over a large area of the Caribbean Sea, with 3,000 personnel involved with the search, returning no results. The exact cause of the crash remains unknown, though it is speculated that the plane's altimeter gave an incorrect reading due to the low surrounding barometric pressure. Although four hurricane reconnaissance flights have been lost since operations began in 1943, Snowcloud Five remains the only known loss of a reconnaissance aircraft as a result of a hurricane in the Atlantic basin, with the other three occurring as a result of Pacific typhoons. Yucatán Peninsula As it approached the Yucatán Peninsula, Janet passed over the Swan Islands north of Honduras as a Category 5 hurricane on September 27. The hurricane caused rough seas, and strong winds uprooted trees and antennas. After gusts exceeded an estimated , officials on the islands took shelter in a Navy seismograph building. Though no deaths were reported, Janet destroyed almost all buildings on the islands. The U.S. Weather Bureau and Civil Aeronautics Authority requested food and supplies for 82 people on the island after the storm passed. Quintana Roo After passing the Swan Islands, Janet made landfall on the Yucatán Peninsula between Corozal Town, British Honduras, and Chetumal, Mexico, at 1700 UTC on September 28. At the time, it had winds of . Hurricane-force winds were reported for two hours preceding the hurricane's landfall, with numerous pressure readings below . Roads and crops on the peninsula sustained heavy damage due to Janet. In Xcalak, Quintana Roo the strong winds from Janet flattened the port's infrastructure,
