Thrust reversers are only deployed after the plane has touched down. Deploying them in flight is a serious violation of safety protocols and will almost certainly leads to a crash.

For civilian airliners, yes. But I'm talking about military airlifters here.

There's this procedure called rapid combat/tactical descent, where military airlifters deploy their thrust reversers mid-flight, alongside engaging spoilers and flaps while pitching nose down during approach to and/or landing at destination airfield or airstrip. This is done to execute a quick descent and landing from higher altitudes within shorter durations in order to minimize the window of which the airlifter is being exposed to enemy threats from the ground (mainly human-portable weapons such as MANPADs) in contested/danger areas, while keeping the airlifter from reaching Never-Exceed Speed to avoid structural failures due to pitch down-induced over-speeding.

It's like slamming the brake mid-air, which is why mainline civilian airliners usually don't come with such feature (except the Soviet examples pointed out by @sheogorath above). And as long as the airlifter is designed for executing such maneuvers and the pilots are properly trained to do so, then there is no problem.

Here's one of the videos of a C-17 engaging thrust reversers in mid-air:


And here's what it looks like from the cockpit (another C-17):


So my question in the initial post is on whether the Y/YY-20/A/B are equipped with the same feature as the ones on the C-17. Would be pretty cool if the Y-20 family does.

Y-20B spotted again, with sound.
