Not sure how the airliner-based mil platforms deal with it.
I think that as I was passing the runway midpoint doing a high speed hydroplane I'd have been CALLING for a departure end barrier, just from force of habit..

Alas.....nothing to help stop a -737 barreling down the runway in their case

Perhaps a very large Guppy net?

I’d probably get an infraction if I call you an idiot so I won’t.
You need to go away.

Here's the thing: we know what you tell us. You're asked, so you make something up: you're an investor for Boeing, you say. Now you tell us that you said this because you were "constantly asked."

You lied, then? This is how you want to be known?

You're clearly not what you claim, and you sound a lot like a reporter. You're not one of the airliners.net nimrods, are you?

A target speed over 160kts is normal with a heavy 737-800/900 in gusty winds. My personal "best" was a target of 165kts landing Rwy 29 at EWR in a 737-900ER.

Asymmetrical reverse is assumed when one T/R is inoperative. The performance penalty is just under 500' of landing distance with one T/R inop. The yaw is minimal.

Where does that come from?

The speed looks about right for the conditions but would depend on their actual landing weight. At max landing weight Vref would be around 151kts plus a max wind additive of +15kts.

Where did you see that they landed at other than idle? The 3 seconds for the speed brakes to extend would also be normal, especially considering a wet runway.

The real key here is the braking action. If there was moderate or heavy rain associated with the storm, on the ungrooved runway, Medium, or worse, braking action would be expected. At Medium, required runway would likely have been over 9,000' (depending, again, on weight). If you only have 7,800' available it isn't going to end well.

Except you’re not supposed to add to Vref for a gusting tailwind.......

Does the 737 have a 1 or both TR inop chart?

That really depends on crosswind.
