How did the recording engineers make the drums sound like there's an air gun blowing in the drums?
You can hear it in the opening 10 seconds of Styx "Father OSA"

And I think the effect is used, but not as dramatic, on Shooting Star's "Last Chance" on the first drum fill response to the music buildup at 4:36 to 4:39

If I wanted to create that effect using Addictive Drums 2 (AD2), could it be done?

The Styx one sounds like a stereo flange to me, if you're talking about the whooshy thing that's going on during the snare buzz roll.
 
I think if you poke around the presets in the Sonitus Modulator you'll find something like that.

I just threw the Sonitus Modulator on my drum bus using the "Classic Sweeping Flanger" preset, did a little Export and put it up on BandLab.
 
Is this what you mean?

That sound seems like basically a flanger - mostly in the  hi frequencies.  But speaking of airgun (in the low frequencies) Addictive Drums has a sine pulse wave as one of its sound options for the "Flexi" slots.  Try mixing that in selectively with some of your kick and low tom notes for a blast of air out of your speakers.  Not too much.

That was nice of you, Erik, to go through all that for me.

I think I can hear some of the effect, but if you could record your sweeping flange on a snare drum roll that lasts several seconds, and also a fast roll of sweeping drums (i.e. up or down all the toms, no cymbals) I could make a better judgment.
 
In the Styx song, the effect is so dramatic, it seems like the drums are flying through the air.  I suppose perfect use of panning and volume control might have lent a hand in that as well?
 
But regardless, you think that's what the recording engineer did for the Styx recording back in the mid-70s?  Pretty innovative.

Thank you for that bit of information, BRainbow.  I own AD2, but have not yet learned how to use it.  I just cracked the Manual tonight and am going to tackle it, finally.  

The free Melda MFlanger using the "Simple" preset does a nice job with drums.  Gets a spacial, whooshy effect, with some nice airy tails on cymbals.

Ah, yeah I know exactly how that was done! That's the inimitable signature sound of the EVENTIDE Digital Delay
It can also effectively be accomplished using the delay section on the Eventide UltraChannel plugin.

Here's a snare roll for ya:

At this point, I think we have a consensus, it's a stereo flange. The aforementioned MFlanger from the MeldaProduction Free Bundle (essential to have for many other reasons) would actually probably be my first choice, but Sonitus Modulator is something that we all already have.
 
UltraChannel would also get the job done, it's a fine plug-in, I own it myself, but you can save $250 if you try Modulator or MFlanger and one of them works.
 
Just call up the presets, fiddle with them, and you'll find what you want. MFlanger will even sync the sweep to the tempo of your song.
 
As for the tom roll, that might be a combination of things in addition to the flanger, including some good ol' panning. But start with a stereo flanger, and tweak it so that the stereo movement is in time to where you want the center to be.

Thanks all for your responses.  And again, Erik, for taking the time to do the snare roll example for me.

Much appreciated!
