You may have heard the sound of fighter jets overhead in the Portland skies recently. That's because the Navy's F/A-18 Hornet planes are in Portland for a training mission with the Oregon Air National Guard.
Colonel Jeffery Hwang is with the 142nd Fighter Wing. He says they're practicing something called 'dissimilar air-combat training'; planes facing off against many different types of planes.
"It's just not one against one airplane which is fairly rare in the real world. Usually it's a much more of a higher order of complexity than that," said Col. Hwang.
Colonel Hwang says large-scale combat with hundreds of planes usually takes place on the first night of an air-campaign.
All combat training takes place over the Pacific Ocean or over the desert in Central Oregon. The two-week training-session at the Portland air-base will end on August 22.
