it's seems to be a engine fart due to excess of power beyond its limit - any alive engine or creature could experimente such thing, try lift something too heavy and your back escape valve works to relief the pressure -

WTF?`He drives BACK???

[jonnybee48]

Hmmm, I've never been a great fan of reverse thrusters, as the mechanisms are quite involved and prone to a lot of vibration and heat stresses; however I appreciate that without them, many aircraft woud be unable to operate from shorter strips around the world. I do have to say, though, that using them to drive the aircraft backwards is taking things a wee bit too far; the phenomenon of heavy fallout adjacent to the air intakes is indicative that the airflow does become very unstable - QED.

just a compressor stall

[Helicopterpilot16]

Its not a bird or a rock or any FOD, This is what is called a compressor stall, This happens due to a disruption of airflow in the intake that stalls the compressors. Many times no damage occurs. If this had been a bird strike, depending on where it hits will cause allot more damage. The reason it occurs on the C-17 more often than any other jet is because they are doing a power back maneuver. The turbulent airflow in front of the engines caused this. There is many other videos of this happening

@Helicopterpilot16 Better yet as I watch this again I see in the intake a wall of condensation building due to excessive low pressure. This also causes a compressor stall.

yes bird stirke!

compressor stall

maybe a stone.

but, i don't see nothing.
