Blue Angels Question(s)

Our family went to the airshow in northern California last weekend. It
was a blast, to say the least. It blows me away to think about the
things people can do with planes and that they can have the
where-with-all to pull off some of the manuvers they do, and under the
G's they are pulling at times!

The Blue Angels were incredible, as were the rest of the performers,
but I left the show, as I'm sure others did, scratching my head
wondering how they do some of the things they do without tragic
results.

I heard that in some of the tight formation flying, they get as close
as 18 inches to each other. If this is true, and I have no reason to
believe it isn't, I have to wonder if they ever bump into one another?
If they were to bump into one another, would that be catastrophic, or
would they merely make contact and separate back into position? They
are all flying in the same direction, and at the same speed, so it's
conceivable that contact could be farily incidental.

Another question I had was regarding two Angels flying in opposite
directions and crossing by each other at a combined speed of 800 mph.
Do they have equipment on board that gives them precise situational
awareness, or do they use ground references? My thought was that one
of them could be lined up to fly right down the runway center-line, and
the other could line up just outside the runway which should guarantee
separation??? Their timing, so that they cross right at midfield is
amazing!

They put on an incredible show, and I'm glad my kids got a chance to
see them. I hadn't seen them in about 20 years, so I forgot how much
fun they were to watch.

In a previous article, "three-eight-hotel" said:

A few months ago two Thunderbirds made contact, and one knocked the
missile rail off the other. Nobody was hurt and everybody landed
successfully.

Snowbirds usually use the two edges of the runway.

"While you're waiting, read the free novel we sent you. It's a Spanish story
about a guy named `Manual'" - Dilbert

My impression is that slight contact during the tight formations is not
all that uncommon, and not generally a real problem - Just a bit of
touch-up painting required now and then ;o)

As far as the opposing pass maneuver, the aircraft are not lined up
horizontally, which is not really evident from the crowd line. Thus,
when they pass, they actually appear much closer than they really are.
Of course, at a closure rate of 1000mph, it wouldn't take much of a
mistake to turn tragic...

The midfield crossing maneuvers are done with a combination of site
reference points, speed control, and radio calls (from the flight
"Boss" flying plane #1). Presumably, all aircraft are flying at the
same speed, in different directions away from show center. At a
designated time/location, "Boss" makes a radio call so that all
aircraft climb (again, at a designated rate). Another radio call
signals the break at the top, where all aircraft decend toward show
center, again at identical speeds. If all goes well, they cross (at
slightly different altitudes) at show center. I've seen them get it
right, and I've seen them get it no-quite-right. )

Radio calls are used throughout the show, between the 2 "solo's" and
the diamond-guys, mostly from "Boss" - "Smoke on, ready, now" -- "Smoke
off, ready, now" "Up we go... a little more pull" "coming by show
center!" "prepare for the left echelon roll..." etc... etc... etc...

Get a radio scanner that can pick up military air frequencies, and
enjoy the show with a whole new perspective!

Yes, they do "bump" once in a while in the formation. There have been
numerous sheet metal "benders" through the years. Naturally, these are
wingtip hits laterally rather than nose hits :-) I remember one of these
occasions quite vividly during the 73 season.
The flow patterns in the diamond are unique to close proximity similar
aircraft. I say similar because in a close Diamond of dis-similar aircraft,
the flow patterns would not be as predictable.
Tip vortices on the left and right wing positions in close tend to cause a
roll away from the opposite aircraft and have to be countered. You can
really feel this as you get in close.
Lead and the slot position have their trim affected as the slot sticks his
nose in where it should be. Lead can actually "feel" the slot in position
and knows by his trim change if the slot slides out too far. The trim change
is nose down for the lead and nose up for the slot, again caused by the flow
patterns.
It's not nearly as smooth in the Diamond as it looks to you from the ground.
There is a lot of movement going on in the formation, especially through
rough air. It takes intense concentration to hold position.
On the cross over question. They use pre-selected hack and checkpoints
briefed by photo recon before the show as well as radio calls when visual.
Timing on the high show bomb burst is a hack call down from lead to the
split S pull on his cadence. There is a visual call by each opposing
aircraft (lead/slot) (left/right wings) and adjustments made during the
downside recovery for altitude and airspeed to seek co-cross at show center.
Naturally, both sides of the runway are used. It saves a hell of a lot of
sheet metal work after the show :-)
Hope this helps a bit.

I read somewhere that during the Korean war, a wounded
plane/ pilot was kept on course to a water bail-out by
bumping the wing to keep the wings level. Any truth to
that?

Sounds like Bob Pardo's little "adventure" in Viet Nam. He lives out in
Colorado today.
Bob literally "pushed" Earl Aman's damaged F4 most of the way home with his
own F4's windshield by getting Earl to lower the tailhook and snagging it on
the base of his own windshield.
Truly a magnificent feat.
I think Aman still lives out near San Antonio last I heard.
Don't know about Korea. There was a story that came out of Korea involving
two pilots flying F9F's when one talked the other back to the carrier.
Mitchner did a story on it. "Men of the Fighting Lady" with Van Johnson and
Dewy Martin as the two pilots involved.

I've seen that movie, a good one. Also a movie, Hunters
with F86.

Bridges at Toko Ri is good too.

I have a great affinity for "God is My Co-Pilot" naturally, as I knew Scotty
personally, but my all time favorite air movie has to be "12'o'clock High",
and strangely enough, it's not the air sequences I liked so much in the
film.
The opening sequence with Dean Jagger, the mug, the bicycle, the fence, the
airfield, then the flashback, has to be one of the finest segway sequences
ever filmed. The ending as well, coming back to the present with Jagger
leaving as he came in on the bike truly put a master's touch of film making
on this picture.

If you think the movie was good, read the book -- ten times better than the

My question for a long time has been, how do they keep their speed
synchronized so well so they can maintain such tight formations? It seems to
me that small variations would have to creep into their engines, requiring
micro adjustments to the throttle settings in flight. Do they have that
available, or are the engines so well maintained that X% of thrust on Bird1
is _exactly_ the same as every other?
