Possible drone over airport this evening

Was travelling A89 towards the airport between 2100 - 2145. Could see a few flights taking off but the last two maintained low altitude which i thought was odd. Then 2mins later there was a bright red light breaking through the clouds, itd flash, pause, flash, only with a red light. Did anyone else witness this? I had my kid in the car who also seen it, we pulled into McDonald's but by then it had gone.
