I would also like to know why costly aircraft under maintenance are maintained in such vulnerable parts of the country, as well as why they were not kept in weather-proof underground hangars.
The Air Force should be required by the DOD to build Concrete and steel Aircraft shelters like we have in Saudi and in Europe.
As far as putting them underground. That's not going to happen, especially in at bases on the coast of Florida.
If you dig down 6 feet your likely to hit water.
