In west Germany entire squadrons were tested with this system because the Soviets would've annihilated the airfields or nuked them before you could shout AIR-RAID! But when you launch more than one plane with rocket boosters the amount of smoke left behind is so tremendous it's impossible to launch another flight untill the cloud has dissipated. Do you remember the last Shuttle take-off? I guess that's the amount of smoke an entire wing would generate.
Now it's too late anyway. You can probably think of tactical advantages to decentralized air squadrons being launched from the middle of forests, caves, from under the sea. It just isn't required anymore.
