BY A STAFF REPORTER: The United States flew a supersonic bomber over supporter South Korea as part of an enormous concerted upstanding exercise involving hundreds of warplanes in a show of force meant to blackjack North Korea over its shower of ballistic bullet tests this week. At least one B-1B bomber shared on the last day of a common US-South Korea air force exercise that wrapped up on Saturday, South Korea’s defense ministry said. South Korea’s service also said North Korea fired four short-range ballistic dumdums into the ocean. The watchful Storm exercise – involving about 240 warplanes, including advanced F-35 fighter spurts from both countries – has touched off an angry response from North Korea.
