I posted this same thread on Combat Ace forum.
The links below correspond to three short videos taken by Hernán "Cruz" Casciani during the "Ceibo 2005" joint exercise.
The first two, show 4 FMA IA-58 Pucará on the Take off run, the other shows two Mirage also taking off. Man, I love the sound of the Pucaras' engines
Pucaras taking off Another pair of Pucaras taking off Deltas taking off These videos were published on the
ECV 56 Cóndor site.
Enjoy.
As an added bonus,
this link corresponds to an uruguayan T-37 taxiing.
