Wow....out of airspeed, altitude and ideas. Appears to be a UH-1Y.

They surely neglected the 2-minute cool down - Shame on them!

No need to fast-rope when you're sitting on the ground!

I agree with Winnie... two blades on the tail rotor and the main rotor hub configuration give it away as being a Bell 412.

Sorta hard on the Troops....having to step up to get off the aircraft while looking at a piled up Fast Rope!

SAS,
I thought the Fast Rope acted well as a cushion for the skids! I do feel sorry for the assault team, after gathering themselves I’m sure they wanted to direct their assault at the poor guys that just dumped them on terrafirma !

Is this a good example of vortex ring state or settling with power?

Most probably VRS but a clear example of what happens if you don't get your power in early enough towards the end of a quickstop.

It depends when you think he ran out if power - was it before the descent started and he didn't have enough for OGE, drooped the NR and began to descend (SWP) or was it as he hauled in the lever while he had low airspeed and an effective rate of descent due to the flare which then led him to ingest his own downwash and develop VRS?

A bit of a moot point really - he just porked a simple manoeuvre very badly and was lucky enough to walk (or limp) away from it.

Not sure he would have caught up with his own downwash as presumably fairly heavy so a large downwash speed. Looks more like poor flying, too aggressive flare with power coming in way too late, evidenced by the ac descending while still in the flare. So poor technique

Hughes500 - poor technique definitely but the harsh flare is one of the classically referenced methods of getting into VRS since the disc is seeing airflow from beneath so as the flare effect reduces and you add power (especially with that much nose up) you effectively satisfy the criteria for VRS. You have a RoD flow, low speed and power being applied.

Not saying it definitely is but it is a strong contender.

There isn't anything about this arrival that can be blamed on aerodynamic effects, unless you are referring to the the airflow between the ears

As an aside Was told years ago by someone from Sikorsky that a CH53 was impossible to put into VRS as it pushed air down so rapidly you couldn't physical catch it up. Personally I think he just ran out of power or air underneath depending on how you want to look at it

Another good VRS training video for the library.
