Preserved at the gate of I Brigada Aérea at El Alto is this T-33, which has fairly recently replaced an AT-6. It was ex French AF 21132. There are two aircraft that have used the serial 634 - the other is a T-33 at Cochabamba used as an instructional airframe. The last of T-Birds were retired as recently as 2017 and seeing this one reminds me of watching them take about two miles of runway to get airborne in the thin air up at 13,600ft when I was last there in 1992. The tail markings celebrate the 100th anniversary of the Bolivian AF

The serial FAB-634 was issued twice. This particular one is former French 21400, it was delivered as F-ZVLD through Glasgow 19 June 1985 and ended up at the PMA as a assembly/disassembly trainer. Seen from 1994 to 1997, it was probably scrapped shortly after. The other FAB-634, former F-ZVLJ/21132 was upgraded in 2001 and flew around in special anniversary colours and is now stored. In case you are wondering: it was seen at the same day, 9 January 1997 as 21132 stored at La Paz! So I suspect it only took up FAB-634 after its upgrade. Also, many T-33s are composites of two halves...
