This was really difficult to guess from the available information. It suggests some changes in the delivery schedule, as otherwise it is impossible to understand why a frame scheduled for delivery in August is convoyed before a HoV to be delivered in April (Asiana's first).
To convey the 6 pieces during the night 12 to 13 07, plan has been modified:
Convoy during that night should be as follows:
-the item delayed will start at 10pm because of the brake down (truck?) at Ordan-Larroque -arrival of that piece at l'Isle Jourdain at around half past midnight on the 13th -reconstitution of the whole convoy (6 pieces) -finish the whole journey (6 pieces) from l'Isle Jourdain to Cornebarrieu.
