A-37 B Dragonfly is absolutely ugly in my personal point of view. The motto for them is "Small but deadly". Fifteen years ago, I experienced its low level with loud noise. Today, some displays at the RTAF museum while some was stored at Royal Thai Aircraft Preservation and Development Foundation.
Two week ago, I went to Chaingmai, upnorth from Bangkok around 800 km. and took some picture of it. Old and careless on a lonely airfield of Wing 41. Please take a look.
