Swift Magic is correct, I know those guys personally. There were 3 of them and they do a lot more than formation.
I owned a Swift for 7 years and 600 hrs. I agree with George on being a Maintenance headache. I would say you work on it at least an hour for every hour of flight. And the Gear is a constant headache.
If I could afford to pay someone to do the work I'd still be flying one today. I also had "spacial disorientation" every time I flew it. And Raced it at Sun-N-Fun. Including Takeoff and Climbout I ended up with a speed of 163 mph over a 60 mile triangular course with a 145 hp engine. Wow, they do have their place. But I did get tired of the 330 mile range in comparison to the 170.

Back in the early 70's I attended the Miami Air Races where a pilot with a beefed up Swift put on an incredible aerobatic show, including numerous hard negative G maneuvers. I could hardly believe what I was seeing.
I heard that subsequently the airplane came apart on him with prdictable results. But it was spectacular !

Any idea how they avoided the attention of the FAA for violating the aircraft operating limitations?N170BP wrote:I know that....gahorn wrote:Basic formation flying is not an aerobatic manuever.
These guys were doing formation aerobatics (loops, rolls,
hammerheads, all the fun stuff).

That's a question I was hinting at in a previous post (other
"non aerobatic certified" aircraft have been displayed at
airshows obviously doing aerobatics). Like the guy who
did the aerobatic Beach 18 routine for awhile (now he
does a routine in a Lear jet!).
For that matter, when Bob Hoover did his routine
in the Shrike Commander.
Did these folks get a waiver from the FAA to "exceed"
the design limitations of the aircraft for the purpose
of aerial displays at airshows? Just wondering how
it works....

Those air show guys probably don't (theoretically) exceed the airplane's legal limits. They do get low-altitude waivers and have to demonstrate air show proficiency to the FAA. (When I competed in aerobatics with my S1S Pitts I got a low-altitude waiver from an FAA inspector who watched perform a sequence). Of course competition aerobatics, unlike air show routines, must stay above 500 ft.

I suspect some aircraft are re-licensed in the experimental/exhibition category or other waivers are issued. Lots of manuevers, of course, aren't really all that stressful. Barrel rolls are a 1-G manuever....the airplane doesn't know which way is up, and a simple loop rarely exceeds 2-G's (same as a 60-degree level turn.) A hammer-head is a low stress manuever no different than a wing-over...provided the airspeed is not allowed to build in the pull out.
Spins and snap-rolls are harder on the airplane than either of those manuevers.

Back in 1975 in my second year of flying I was in Spokane on a trip from Seattle with my '51 170A. While in the gas office a fellow walks up and asks if I'm driving the 170. When I said yes he told me he used to own that plane and that it "sure loops and rolls nice". Not a great thing to hear. At least I found out (probably) why one wing had a bit of a wrinkle in the top skin. I did quite a few spins in that plane though but of course it's approved for that.
