The lobby of the Royal Thai Air Force Museum in Bangkok, features a genuine Northrop F-5 fighter plane (fig.) with the slogan: Nahn Fah Thai Ja Mi Hai Khrai Yam Yih (น่านฟ้าไทย จะไม่ให้ใครย่ำยี), i.e. ‘we will not allow anyone to invade Thai territorial air space’.

The Air Force Museum was established in 1952, in order to collect, restore, preserve and exhibit all kinds of military aircraft, as well as aviation equipment, that were once used by the Royal Thai Air Force.
