I agree with your synopsis. We might also add failing to arm Speed Brakes which wouldn't be the first time on a B737. You could also suggest the crew hit hard, bounced then tried to land 'smoothly' the second time instead of executing a balked or low energy go around. I can see a crew falling behind, rushing things a bit, and just when it should all come together they ended up crossing the fence high and hot and it all went out the window from there.

The automation comment is due to an earlier comment in this thread. I happen to be of the opinion automation DID play a role in this but we'll have to wait and see.

1. Hot and high, for whatever reason
They didn't maximize the Automation. VNAV, LNAV and VTK

2. Carrying speed and/or height over the thresh
Automation (including A/T) would have hit the crossing height at the proper height and speed.

3. Touches down in a little, maybe 2500'
Should have used A/P A&B, A/T

4. 50' high is another 1000', minimum
Agreed. But, by then it was too late to stop on what was left.

5. Non-grooved runway
Indian DGCA and Federal gov't guilty of not making this airport safer when they had the chance.

6. Lotta water has fallen, maybe > 30mm in the hour
Crew evaluation of Threat and Error management upon receipt of ATIS or WX from ATC.

7. Water on the runway is > 2.6mm setting it up for..
Threat and Error management again?

8. Reverted rubber hydroplaning
Threat and Error management. Crew should have touched down at the proper point at the correct speed with Auto Brake High and Speed Brakes armed.

9. Gets to his 9 times the square root of the tire psi speed
Had at least 45 minutes before the landing to look at that. Threat and Error management?

10. One tire stops spinning
I think they thumped it on and bounced. Possibly blowing a tire in the process.

11. Steam builds up under the tire
They tried to recover with a slight increase in power to soften the second touchdown and therefore increased their forward speed and touchdown point. I've had a right main tyre blow on landing as it rolled through a large puddle of water. You could be right.

12. The rubber shreds and the tire blows
Possibly a tyre blew from the initial thump onto the runway.

13. Big swing
Okay. That's likely.

14. Pilot knows this is not cool
That's for sure.

15. Tries to execute a touch and go
Yup. Below V2 for the go around with an early rotation.

16. Now they're here, on PPRuNe
Yes. Now they're here on PPRuNe

P.S. Your opinon DOES matter.
