The recent New Year celebrations in Thailand resulted in reports of dangerous situations for aircraft in Thai airspace.
This was reason for the Thai government to start a cooperation to limit these threats. Representatives of the Transport Ministry, the Interior Ministry, the Defence Ministry, the Tourism and Sports Ministry, the Education Ministry, the Culture Ministry, the Royal Thai Police Office, the Public Relations Department, the National Office of Buddhism and the Bangkok Metropolitan Administration signed a memorandum to cooperate.
They agreed to cooperate to control the launching of sky lanterns and bang fai rockets (a competitive firings of home-made rockets during a traditional festival). Almost 48,000 rocket launches were reported in advance but many rockets were even reported at altitudes of 20,000 feet. Also many rockets were fired without prior notice and outside the festival season.
