The bomber formations are extremely difficult to hold together, especially when taking off where you have to steer around hills. You'll also lose your drones while just climbing out at alt-x, where the drones drift back too far. It is difficult to get them to catch back up again. The problem seems to be worse when taking off with heavy loads, such as with 100% fuel. We don't need the extra challenge when flying buffs and in real life, the lead pilot wouldn't have to work just to stay in front of the planes following him. Each plane in the formation's pilot would follow the lead plane. With the new bigger towns and more spread out airfields in AHII, it is critical to try to reach the target with your formation intact.
