Thank you to all for your answers.
I have done 2 counts for estimate, how many people needed for take up a field protected from at least 5/6 fighter.
1 Bomber for Fighters Hangars.
1 Bomber for Bomber Hangar and Carts.
1 Bomber for ack and fuel.
1 Bomber for tower and the other structures
1 Bomber like substitute in case of failure of the first throwing or of loss of one of the Bomber during the transfer.
5 fighter of escort for the bombers
5 fighter for aerial superiority
2 Thiphoon for the carts and the M16
1 or 2 C47 for goonie
Result:
18 airplanes for take a field defended from 5/6 fighters.
This one because, the Hangars, they remain inactive, for once too limited.
Yesterday I have tried the times, once performed the bombardment and destroyed the Hangars, the necessary time to return back, leave again and be in position for a new strike, was exactly the necessary one to the Hangars for be regenerated.
Aaaarrrghhhhh. the life is becoming hard.
Cheers.
