Of course planes would be better if they were like birds. No government regulation, self piloting, instinctive self preservation,self repairing and when you need parts they are really cheap.
Birds have better pilots; the pilot is, literally, “at one” with the flying apparatus.

So the bugger flies from Alaska to New-Zeeland , passing the Fiji Islands without taking a nap , a sanitary stop nor a beer. Flying even around those.-but very economical=1 kg bird can fly continously 10000 km on the 0.5 kg fat,
NO water !
There are always exceptions: the ball player in a Cirrus took a wrong turn over the East River in NYC; a B-25 in the Empire State Building...Are they? There are a bunch flying into windows here. Some survive with minor damage, some not.
As luck will have it: no airplane as of yet.
