A search was launched on Monday night after a report of a red flare being seen off the South Pembrokeshire coast. A 999 call was received at the Operations Room, Milford Haven, at approximately 11 pm, reporting a red flare being seen between Stackpole and St. Govans Head. The St. Govans coast rescue team was called and made a thorough search of the area. Radio transmissions were also broadcast via the VHF Channel 16 system for any sightings of the flare or persons in distress. During the coastguard search on Broadhaven South Beach, the residue of a fire was found and upon further investigation a man from Caerphilly, staying at a local caravan park, stated he had set off a 'Thai Fire Sky Lantern' at the time the 999 call was received. All the actions were checked out and the call was treated as a false alarm with good intent. Thai fire lanterns are a new feature at firework displays at the end of parties, weddings etc. The paper lanterns, fuelled by a wax paper wick, come in various colours, including red. They are lit on the ground and rise slowly and majestically into the air creating an amazing sight when launched in multiples. They originated in China some 1,800 years ago, and were used to convey the spirits of the dead into heaven. "These lanterns are becoming more popular and may be seen around the coast during the summer," said Angie Smith, DPRO, Milford Haven coastguard. "Should anyone see what they think is a flare, or light going up into the sky near or off the coast, do not hesitate to call the coastguards; we will always investigate."
