Bustr, if you continue in the same vein, this will be the last post I direct to you. Stay on topic. Your criticism fall flat on these ears; I don't care about your opinion or your cheesy, far-fetched metaphors. Everyone else here has contributed to the topic appropriately. If you have something useful to add, please, you have my attention. Otherwise, go somewhere else.
Zimme, Greebo, good ideas. I think the tow plane idea may be a bit clunky. A Lancaster won't get high enough fast enough to make a glider any useful. However, a cargo glider could be a good idea. Say you launched a glider from 35k. The tow plane could exit and leave the glider to its own devices. It won't be heard and from that alt, it could possibly be decently stealthy. It could make the drop and then the pilot could either end flight or land or bail above the supply drop. Once the supply drop hits the ground, it could spring up into a FOB. Since this was a friendly field, the pilot wouldn't be counted as captured if it's in enemy territory.
These FOBs would be weak and not heavily defended. This will leave defense up to the ones that utilize and created it. It would be strategic, tacticle, and challenging to maintain. It could provide a new element to the fight and help mix things up a little. Essentially, it would work as a temporary respawn, rearm, and observational site but it would be very limited. It would have its own radar ring and could advance the eyes of friendly forces.
In practicality, the ones who would use it have to defend it. The ones that see it will want to destroy it. If you agree or if you want to add to the idea, let's hear it. HiTech won't be inclined to consider unless there is a considerable agreement on the topic.
Second idea: dated and cheesy though it may be, how about zeppelins? Stationary with radar capabilities. Not as large a radar ring as a base but it would help extend the eyes of defensive forces. They could be temporary, lasting only 5-10 minutes but they provide insight into what is going on in the airspace. They could be deployed to reach 10k, no higher. Because they bring a good bit of heightened SA, they would need to be vulnerable, as is their nature. Pilots that stumble across one could shoot them down, earning attack damage points for that sortie. Like I said, it's not likely to be a good idea but it was used greatly in WWI.
I really do have an incredible passion for this game and I would love to see the next evolution of it. I want to bring in new people and keep the people we have already. These are just my contributions.
