Look inside the canopy.
You can see a loop at the top of the ejection seat.
This is the primary
ejection seat handle. The pilot pulls this handle to activate the ejection
sequence. However, there's a lot more to ejecting from an airplane
than just pulling the handle and shooting out of the airplane. When
you pull the handle just 1/4 of an inch, the sequence begins and cannot
be stopped. First a canopy breaker, two arms attached to each side
of the upper part of the seat, pop up and breaks the canopy loose from
its frame. By this time the pilot has the face curtain which is attached
to the ejection seat handle, over his face.
Next the solid
rocket motor fires. It's not a rocket like you see on TV where
the rocket gently lifts the pilot off of the ground. This rocket
acts more like a cannon shell exploding under the ejection seat. The pilot
is ejected very, very fast. As the rocket blast pushes the
ejection seat out of the plane, the tremendous G force causes the pilots hands and
the face curtain to be pulled into his lap.
The face curtain,
flight suit and seat frame are very important. If a pilot ejected
at 600 mph without these protective devices, the tremendous force of the
wind at that speed would first break both of the pilots arms, his legs,
his neck and his back. His body would then receive third degree burns
by the tremendous oxidizing effects of the wind. He would not have
a good day.
Back to the ejection
seat firing sequence. Before the pilot can eject, he must have previously set
up his seat and rudder pedals to the proper position. These jets
are like a fancy car with electric seats, you hit the button and the seat
moves up and down. This is not designed primarily for comfort but
for the pilots safety. He must move the seat and rudder pedals to
a position where he cannot put his fingers under his leg. If the
had the space of just the thickness his fingers between the seat and his
leg when he pulled the ejection handle, the ejection force would break
both his legs just above his knees. Many times upon ejection a pilot
will break something anyway, his arm or his leg. Ejection seats are
a last resort, only.
When I went through
ejection seat training, I had to do this for a back seat license in the
TA-4, we watched many videos on the ejection process. Just like on
TV, you see the guy fly out of the aircraft neat
and easy. But when they showed the process at normal speeds it looked more
like something out a comedy program. The pilots shot out of the airplane
at a tremendous speed way faster than what looks real. The films
you see in the movies are slowed down to make the ejection process look
real. I heard that the slowed down Bruce Lee's kicks to make them
look real also.
One more thing.
There is another handle on the seat between the pilots legs. This
is also an ejection handle. The pilot may pull this one if he doesn't
have time to reach the handle above his head. The bad part of pulling
this handle is that he eliminates the face curtain protection that the
upper handle provides against the horrendous wind.
The Russian's
had an additional solution for aircraft ejection's performed at near and
above mach one. They place an air deflection device between
the pilots feet. When the pilot ejected, although very small,
this device would block the air hitting the pilot providing added safety
against the air blast.

Subject: FW: Who
Packs Your Parachute?
Charles Plumb
was a U.S. Navy jet pilot in Vietnam. After 75 combat missions,
his plane was destroyed by a surface-to-air missile. Plumb
ejected and parachuted into enemy hands. He was captured and spent
6 years in a communist Vietnamese prison. He survived
the ordeal and now lectures on lessons learned from that experience.
One day, when
Plumb and his wife were sitting in a restaurant, a man at another
table came up and said, "You're Plumb! You flew jet fighters in
Vietnam from the aircraft carrier Kitty Hawk. You were shot down!"
"How in the world
did you know that?" asked Plumb.
"I packed your
parachute," the man replied. Plumb gasped in surprise and
gratitude.
The man pumped
his hand and said, "I guess it worked!" Plumb assured him,
"It sure did. If your chute hadn't worked, I wouldn't be here
today." Plumb couldn't sleep that night, thinking about
that man. Plumb says, "I kept wondering what he might
have looked like in a Navy uniform: a white hat, a bib in the back,
and bell-bottom trousers. I wonder how many times I might
have seen him and not even said 'Good morning, how are you?' or
anything because, you see, I was a fighter pilot and he was just a
sailor."
Plumb thought
of the many hours the sailor had spent on a long wooden table in
the bowels of the ship, carefully weaving the shrouds and folding
the silks of each chute, holding in his hands each time the fate of
someone he didn't know.
Now, Plumb asks
his audience, "Who's packing your parachute?"
Everyone
has someone who provides what they need to make it through the day.
Plumb also points out that he needed many kinds of parachutes when
his
plane was
shot down over enemy territory -- he needed his physical parachute,
his mental
parachute, his emotional parachute, and his spiritual parachute.
He called on all these supports before reaching safety. Sometimes
in the daily challenges that life gives us, we miss what is really
important. We may fail to say hello, please, or thank you,
congratulate someone on something wonderful that has happened to them,
give a compliment, or just do something nice for no reason. |
