The picture of all the Yaks and Nanchangs in close formation on
www.flyfast.org got me thinking about something.
When there are so many planes in very close formation like that, and like the Snowbirds, or Blue Angels, etc, is there a SNAFU maneuvre, and what I mean by that is if everything goes wrong and the formation has to be ended immediately, is there a quick break that each airplane is pre-assigned to do?
Please fill me in, I've always been curious.
Cheers,

David The following is out of the RPA Formation Manual. There are additional procedures, for "Knock it Off" (KIO) calls, "Blind" Calls, and extensive procedures for "Lost Wingman" calls, but this gives you an idea. Much depends on if the formation is straight and level, in a turn, in a climb, arrival, departure, etc.
1.10.4 Formation Break Out Procedures
The purpose of a break out is to ensure immediate separation
and to avoid a mid-air collision.
Lead
If a wingman has broken out of the flight, you may continue
the current maneuver with the current power setting to aid
in aircraft separation. If the wingman is in sight, you will be
directive and maneuver to obtain separation based on the
wing pilot’s altitude call or visual contact.
Wingman
As the wing pilot, you must break out of the formation if
you:
-Lose sight of your lead aircraft
-If you are unable to rejoin or stay in
formation without crossing directly under
or in front of Lead
-If you feel your presence in the formation
constitutes a hazard.
-When you are directed to do so by Lead
If you have lost sight, clear, then break in the safest direction
away from the last know position or flight path of Lead and
other aircraft. One technique: “look for blue sky and pull” is
appropriate for many situations (see caution below). Call
the breakout and your altitude:
“Raven 2, breaking out, climbing to 4500 feet.”
After gaining safe separation, you should confirm that Lead
is, or is not, in sight and transmit “visual”, or “blind” IAW
with this chapter. If you have reacquired Lead, remain in the
same general area but make no attempt to close on the fl ight
until Lead directs you to rejoin.
WARNING
The wing pilot may encounter a hazardous situation
in which an aggressive break out is inappropriate.
For example, if the aircraft drifts into a
position dangerously close to Lead, an aggressive
breakout may possibly result in collision. In this
situation, the wing pilot should move away from
Lead, using smooth and positive control inputs.
5.8 Breakout
Leaving formation is the same in three- and four-ship formations
as in two-ship formations, However, if number 3
leaves the formation, number 4 will follow number 3 at a
safe distance to maintain element integrity if safe to do so.
In all cases, the Flight Lead will provide adequate altitude
separation and direct the rejoin as required. An aircraft that
has left formation will not rejoin until cleared to do so.
