I always assumed military aircraft didn’t have TCAS or any other such technology that could give away the position of the aircraft. But thinking about it, why not? They do have transporders, they just have an off switch for them.

So I don’t know. Maybe they don’t have TCAS, maybe they forgot to turn it on. Either way, TCAS probably wouldn’t work at low altitude during a landing.

We will probably have to wait for the accident report.
