I hope its not too late but i had an idea to go with the 3 formation. I was thinking because thers gonna be 10 pilots after the formation the formation splits up into pairs. One behind the other like this.
Pilot 2(rear) will be the smoke provider and Pilot1(front)will be the eyes and ears to help Pilot2.
Sorry for the crap pic i did it with paint.:) Anyway flight C,D and E will fly in straight horizantal lines to form part of the 3. P.S. ive used different couloured somoke and planes to show their flight path. Flight A and B will crossover to form the rest of the 3. The smoke will need to stop almost simultaneously after the smoke has stopped pilot1 will perform an aileron roll dropping a set of flares about every 90 degrees.
Here are some negatives:
*Not all teams use the same smoke coulour.
*Not all teams will have smoke pods on the fuselage.
*Not all teams will have enought flares left.
I dont know whether ive explained this properly so tell me if i need to go over anything. For those who did understand me:) tell me what you think.
Thanks,
