Birds and aircraft
I'm only SLF, and a Birder. For what it is worth I remember flying out of Ciampino on Ryanair last winter. After take off power was reduced (noise regs as we flew over the city) We could'nt have been higher than appx 1000mts when I saw a Yellow-Legged Gull pass under the aircraft only 100mts distant, I commented to my partner how close it was, and how it would'nt be nice to hit one- as they weigh about a kilo.
Sounds like good airmanship to me.
