1776,
What Ripsnort states is, in part, true. There are sectors, like everything involved civilian air transportation, possibly cargo too, that is being severely hit. Not only aircraft builders, but operators, airport owners, hotels (especially the ones near the airports),tourism as a whole, that will be terribly hit by this crisis.
On the other hand, there will be sectors, like the obvious defense, electronics, semiconductor, internet security, criptography, that will get a boost.
It's way too early to jugdge, and the final outcome will depend very much on consumer attitude and nerves agains panic. The overall impact will be, IMHO, recessionist, in the short term, and expansive on the long run.
Cheers,
Pepe
