Now if they measured fuel used with the same accuracy as their comparison of driving with the air-conditioning on & windows up vice a/c off & windows down, then I might be more apt to believe.

Just my thoughts about the analysis. The rest of the footage was great!

Thanks to Chuck Newman's excellent work, we had fuel flow to the 1/7000th of a gallon per hour...how much more accurate do you want it?

The savings were higher than reported, but I'll let the NASA guy (Steve Smith on this forum) defend the science...I are just the pilot.

I have not watched the show yet but have it on DVR.

Efficiency comes in reducing induced drag. Works like having a larger aspect ratio. Think of them as increasing your wing span. Lead plane gets the effect as well as those in trail. I have done studies for the big company as well as read NASA reports from back in the (early) B-52 days.

The Conga line approach didn't look like too much fun

Glad nobody died in the side by side formation...

I do not understand the comment.

The "Skytypers" do it all the time and get paid to fly formation side by side.

All of the formations flown in the show were well briefed and practiced by well qualified pilots. While this particular formation is non-standard for most formation flying, as the camera ship pilot for the side by side flight, I can assure you that these guys were ROCK solid...

My formation experience is limited to one flight as a passenger in a flight where Gary was lead.

I have no idea what I am talking about but that looked dangerous to me.....I am most likely wrong.

Anyway, that was a cool episode and great job guys!

[ed. One of the mods deleted some of these replies w/o my knowledge. I think they are perfectly OK (about safety). Sorry for the hiccup and sure several of the formation qual'd folks with answer your Q's. dr]

Steve does decribe the science in this thread: http://www.vansairforce.com/communit...ad.php?t=79555. Some great comments there, and I chimed in with some observations from the pilot's perspective. Cliff notes:

The benefit to the lead is not inconsistent.
The experiment was very successful, and we gathered some great data.
The conga line was no fun (really!)
Plus more...

Take a look there for more info. This was a fun project!

Cheers,
Bob

I missed it, can you view it on the Internet or are there going to be reruns?
