Its always annoying to post this boards since you are arguinig with idiots who have a dick measuring contest with a faulty ruler.
Evrything can be improved so its better/worse. ATM in this place and time currently planes use more fuel than trains, or trucks and have way worse weight to mile balance than ships also. So they are last in line. If you make the engines better they are top tier. But that wont happen since gravity is good sometimes AKA trains and a alredy existing infrastructure.
If planes were so good at shipping cargo not some prime time jewlery piece USA wouldnt have a large ass road network and not a large ass rail network.
BUT, WHAT IFF, MAY, PROBABLY is all true. But in this place in time no.
