The famous air strike in a fantasy world. There has been some questions about whether the creatures are dragons or pterosaurs. The answer is both, perhaps more. You don't usually run a major air strike with only one type of aircraft in real life, and I presume the same applies in a fantasy world. I guess you could say the dragons, being bigger and slower, are the 'bombers,' while the faster and more agile pterosaurs are the escort 'fighters.'
