The U.S. military's declassified 42-second color footage shows a Russian Su-27 approaching the back of the MQ-9 Reaper drone and releasing fuel as it passes, the Pentagon said. Dumping the fuel appeared to be aimed at blinding the drone's optical instruments to drive it from the area.

My opinion/question/guess:

Dropped fuel will partially vaporize.
HOT EXHAUST from the passing jet.

I wonder why there was not a FIREBALL ? ? ?

Landing at excess weight isn't great for landing gear (and I assume other parts), so most (all?) military jets and commercial jets have the ability to dump excess gas in case a landing is nessecary before the fuel is consumed. There's not really a need to light it, so they aren't placed in a spot where lighting it up, even if unlikely, would be a possibility. Wouldve made for some rad footage though, like when the F111s would light the dumped fuel with their afterburner.

You have to engage the afterburners for dumped fuel to ignite. With no reheat the gas exiting even a military turbofan is not all that hot. The rear of the turbines is a long way in from the end of the jetpipe.

Another thought is that they might have been thinking the fuel would ignite in a bad place inside the drone motor and bring it down. Alternatively, sucking in a cloud of raw fuel might have choked the drone motor of air.
 
I was curious about that myself. Perhaps it was more symbolic than practical.

Ironically, one of the biggest with the most fuel cannot dump it--the B-52.
 
How is it that the Russians are trying to recover it but we aren't. I also agree with the mess up the cameras theory.

The Russians were already nearby. I believe that I heard that the U. S. Navy had no assets in the area. The current line from the DoD is that anything having intelligence value was destroyed. Wonder if Putin is going to pay us that $30 million value of the drone.

Reporting is the fuel dump was on purpose, the collision that bent the prop and bit into the wing of the Ruski jet accidental. No reason to think the Ruski pilots are any better trained than their army. They ever actually go toe to toe with US pilots in F-22's, going to be a lot of burnt up Red Stars littering the landscape.
 
We need to do the same thing with the regular russian flights off Alaska. Especially their bombers.
