There is at least one other documented case of an A320 impacting the runway on both engines and still being able to get back in the air. These aircraft are tougher than people give them credit for.

If they bounced, the wow should register a zero on the radar data, I don't think the gear ever touched the ground. If they retracted, it was probably done before first contact with the ground. However, I don't think the gear was ever down in the first place, perhaps they were constantly canceling alerts, and missed the gear warning, that's a pretty crazy approach profile.

i don’t think the gear was down, so no WOW, no zero.

I've got 1300 hours on the A320 series, I do not understand how they could fail to put the gear down. You've got the horn (heard in the ATC recording) blasting away. Even if the gear was in transit they should have had the horn (I think, it's been almost 20 years since my last 'bus flight).

Well, from what we know so far, it makes you wonder.

About the same amount of wonder/head scratch as how a crew can fly so much of a leg with the gear down.

Good thing is, the latter wasn’t fatal.

If you're way high, pitching down, flaps full, no gear, then overspeed flaps above 177 kts. That's a master warning and CRC. An overspeed master warning can't be cancelled. Too low gear is an aural but also a master warning and CRC. It could be the case the overspeed on flaps during a massive dive towards the runway masked the gear down warning to their ears.

seems plausible given the approach data

Im thinking they fumbled a landing and initiated a go-around in the “TOGA deadzone”, rotated and retracted the gear then recognized the autothrottle wasn’t doing what they were hoping for.....Emirates 521
Settled on the runway as they slammed in full power, climbed out with two damaged engines and the rest is history.
Been done before....

Could be. You are supposed to verify positive rate before pulling the gear though.

But I don't recall the 320 having a TOGA deadzone, as far as I know if you select TOGA, you get TOGA. Sometimes the bus might not let you out of TOGA when you want out, but it should always let you in.

The way you select TOGA on a bus is by manually jamming the levers forward to the stop. You would not expect the plane to do that for you anyway.

I'm typed on the A320 and never heard of a TOGA deadzone. If you push the thrust levers forward, you get TOGA on the A320. No questions asked. Alpha Floor and Thrust Lock are a couple of ways the autothrust would fix thrust output but as you said those are not going to prevent TOGA power.
