Next, the flight section leaders are briefed separately. Each class of canard had a leader and backup leader. The only people who would speak on the radio were the Lead Airplane and the Tail airplane. The exception to this rule was that each flight leader would inform FLD Tower that they were "Long EZ Flight" etc. and would be spacing 30 seconds for departure. WIthin each group, the planes left with 5 second spacing, alternating side to side on the runway.
