Supersonic Stealth

a

This weekend I went up to Oshkosh, and got to visit the EAA airshow. This plane was the most impressive: The F-22, the most advanced fighter jet in the world. A few random facts:

• They each cost $137.5 million
• The plane uses stealth technology and all its weapons are stored internally. The bay doors open in less than a second.
• The plane has a top speed near 1,600 mph, (Mach 2.4). Most fighter jets cannot go supersonic.
• It can also fly very slowly, and we saw it fly by a 90 knots.
• The planes are so advanced they are not for sale to any foreign country.
• The planes have only been operational for about three years.
