During the project‚ the half-hour radars started to show heavy precipitation‚ and as the hours passed‚ the storms got more severe. However‚ the 2000 hour radar was different. At 1930 hours‚ there was the potential of very heavy rain‚ lightning‚ heavy winds‚ and hail in the Omaha radar reading. Only 30 minutes later‚ however‚ the weather in the Omaha area nearly

had lost 1‚700 planes compared to the British losing 900 planes (Staff‚ Spark Notes). The new technology of radar came as a great value. The British could scramble fighters in the right place at the right time as the British built a net of radar stations along their coastline and could see the enemy coming (Staff‚ Spark Notes). Although the Germans made an effort to bomb the British radar stations early on in the war‚ but they gave up this strategy as they believed it was ineffective. This proved

Self-driving cars are being built and are being experimented with everyday. Google has been building driverless cars for a while now. Features the cars will have is a GPS receiver‚ laser range finder‚ windscreen‚ video camera‚ radars‚ and an 160km-range engine. Although the self-driving cars already have all these features‚ it still has glitches that are continuously being operated on to be improved. Driverless cars technology cannot be fully trusted.

In September 2002‚ the USAF decided to redesignate the aircraft F/A-22 to reflect its multi-mission capability in ground attack as well as air-to-air roles. The aircraft’s design was changed again to F-22A when it achieved initial operating capability in December 2005. The decision to proceed to low-rate initial production
