Under or over seat steering?

Ah, but as any skydiver will tell you, by getting out at the top, you
are avoiding the most dangerous bit of flying, namely the landing

But you're not avoiding the part where they put too many skydivers
too far back in a small plane, putting the center of gravity too
far back, and stall/spin into the ground not long after takeoff.
This seems to happen more than it should with skydive operators.
Usually landing is the most dangerous part, but with all the
skydivers gone, the plane is light and has a good safe forward
center of gravity.

So they not only avoid the most dangerous segment of the flight, they
make it safer for the pilot too.

Dave,

Unfortunately there is usually not time for them to get out if the
tail-heavy condition is severe. The plane will very likely snap-roll right
after rotation for takeoff and dive into the ground taking pilots, skydivers
and their uni-cycles with it.

I note that the ASS Grasshopper uses a Terracycle Glideflex stem...


Pardon my ignorance but is this a good thing or a bad thing?

If at first you don't succeed...
Skydiving is probably not the sport for you.

Ooo. I wouldn't want to jump at a DZ run like that. sounds positivly

not so bad in a Reynolds type set up, where the feet are at or slightly
above the hands, you are almost tucked in under the thighs, in that nice
slipstream from the legs. I would guess this wouldn't be more than .5
mph disadvantage.

point out almost straight from the shoulder joint and add little frontal
area. With a praying hamster bar the forearms and hands can be in front
of the chest area thus also reducing the total frontal area. In these
ASS cases, there is the added drag area of the stem and bars but its
effect is uncertain (does the draft shadow around the bars close and
then have to re-open around the rider?) In any case I would concede
that the ASS can have some aerodynamic advantages on high performance
bikes.

That doesn't make a whole lot of sense

Mr. Roberts was commenting on Mr. Crawford comparing USS to USS.

Paul,

I'm beginning to think that you may be one of those totally insane S.F.
persons that jump from around 300 ft. in the middle of a moonless night over
God-knows-where. One of my kids flew those guys out of PAFB many
times....I never did hear how they got back....

Thanks Tom! They must have missed the Smiley! ; )
