Several claims of breaking the sound barrier during the war subsequently emerged. However, the first recognized flight exceeding the speed of sound by a manned aircraft in controlled level flight was performed on October 14, 1947 by the experimental Bell X-1 research rocket plane piloted by Charles ``Chuck'' Yeager. The first production plane to break the sound barrier was an F-86 Canadair Sabre with the first 'supersonic' woman pilot, Jacqueline Cochran, at the controls. According to David Masters, the DFS 346 prototype captured in Germany by the Soviets, after being released from a B-29 at 32800 ft (10000 m), reached 683 mph (1100 km/h) late in 1945, which would have exceeded Mach 1 at that height. The pilot in these flights was the German Wolfgang Ziese.

In addition, the shooter must release the ball within five seconds (ten seconds in the United States) and must not step on or over the free throw line until the ball touches the hoop. Players are, however, permitted to jump while attempting the free throw, provided they do not leave the designated area at any point. A violation by the shooter cancels the free throw; a violation by the defensive team results in a substitute free throw if the shooter missed; a violation by the offensive team or a shot that completely misses the hoop results in the loss of possession to the defensive team (only if it is on the last free throw).
 Question: is it legal to jump on a free throw Context: Cathode rays (also called an electron beam or e-beam) are streams of electrons observed in vacuum tubes. If an evacuated glass tube is equipped with two electrodes and a voltage is applied, glass behind the positive electrode is observed to glow, due to electrons emitted from and traveling away from the cathode (the electrode connected to the negative terminal of the voltage supply). They were first observed in 1869 by German physicist Johann Wilhelm Hittorf, and were named in 1876 by Eugen Goldstein Kathodenstrahlen, or cathode rays. In 1897, British physicist J.J. Thomson showed that cathode rays were composed of a previously unknown negatively charged particle, which was later named the electron. Cathode ray tubes (CRTs) use a focused beam of electrons deflected by electric or magnetic fields to create the image on a television screen.
 Question: do cathode rays originate from the negative electrode Context: Her world is further shocked when Tom asks for a divorce, and announces that he and Jane will be moving in together. Lynette is devastated, and her rivalry with Jane becomes more heated at Penny's birthday party when they continually try to one up each other. Jane then later tries to reconcile with Lynette, but then she begins to choke on a snack. Lynette hesitates to help Jane, but ultimately comes to her aid and saves her.
