TASEA started in the late 80's in Mexico with a fleet of corporate jets and 727-100's. In 1991-92 they leases 737-300's and 757-200's from GPA. In 1991 they took over LaTur who was in recievership and added a small number of MD
-80's to their fleet. Inthe next few years, they changed their livery to yellow white an blue lettering, added 727-200s, DC-9's and a DC-10F. apparently they grew quite a bit but lost two Lears in the early 90's. I don't recall hearing much about them until the 1999 Uruapan crash of a DC-9-30 where 18 people were killed. What ever happened to them. There isn't a whole lot about thew airline on the internet execpt pictures here and an accident synopsis on www.aviation-safety.net.
