The picture of the peel off is actually of the 1900D I’m in. 🙂 That part of the series was shot by the FO in the other 1900D.

That experience was so much fun.

I checked up the registration of that AA on a.net, it’s an ex-Reno Air MD-87. It’s currently with Aeromexico, with the same registration (N753RA).

It appears that the model has a vortilon which was only found on the DC-9-10 or -30 series I believe. Just in front of the main gear you can see the vortilon jutting out.

Here’s a picture a DC-9-10 where you can see the vortilon.

Toilet outflows , Pressurization outflow , …..
these are small valves.

Pressuization outflows can be quite large on large jets.

I know there isn’t any scale on this picture but it’s of the 747 outflow valve.

Here’s a picture I took of a MD-80 where you can see it’s outflow valve full open on the ground. That diameter is roughly 12″.

WD I LOVE that formation shot! whats the story behind it?

It was a delivery flight to the paint shop before we handed over our 1900D’s to their new owner. We did the last 2 hours VFR in formation and took a bunch of pictures. This image was taken as we began our low pass over the airport before calling it a day. I think I posted the full set some where on this forums. If I can’t turn them up I’ll post them again if you’re interested.

Toilet outflows are about as wide as your thumbs thickness so I doubt it would be possible for it to create a contrail as large as that.

This was taken pre-digital so I’m left scanning the picture.

Very nice pictures. I particularly like the Korean Air 747.
