Runway:
Block Requirements:
-Min: 6000 blocks
-Max: 20000 blocks
at least 50% concrete
at least 10% iron blocks
only 1% can be chest, barrels
Fire power: 10
Pros:
-Planes can be controlled 1200 blocks from the Runway
-Chests on the runway will automatically refill fuel and ammo for fighters, zeppelins.
Cons:
-Only 5 Planes are allowed to be piloted at a time under a Runway's control.
-No Protection
-Will only work if it is an unpeaceful town

Aircrafts:
Add:
-When ran out of fuel aircraft automatically descend (for fighters and bombers) 5 blocks per second. Once touch the ground the aircraft will explode. If craft fall on to water it wont explode but float on the surface and damages the pilot.
-When destroyed aircraft explode (for all aircrafts)

Engines:
Block Requirements:
Min: 2 blocks
Max: 5 blocks
Type of Engines:
Propeller: must be 100% wool, 2-10 blocks, 9 blocks / second, 21 blocks / second when cruising
Fighter Engine: must be 100% iron blocks, 3-4 blocks, 11 blocks / seconds, 25 blocks / second when cruising
Engines can be placed by placing a sign on the 2-5 Iron blocks on a aircraft, First line "Fi/Pr Engine", Second Line "Engine [number]" Once all Engines are destroyed aircrafts will stop moving and descend (free fall). If one engine is still working aircrafts will use up fuel twice as fast. (Fi for fighter, Pr for propeller)
When an Engine is destroyed it tells the pilot in chat "Engine number [number] has been destroyed"
(Planes can have 1 engine but travels slowing than 2)





I have no idea if this is possible but if it does who knows
