Japan's Formosa garrison, meanwhile, set the final toll in the Wednesday air raid, the first air bombardment of Japanese territory in history, at eight killed, including three children, and 29 injured. Newspapers published only official communiques which said a few Chinese bombers dropped five bombs at Taihoku and Shinchiku City, missed their targets at the Taihoku airdrome, and killed and Injured fishermen at th nearby suburb of Matsuyama.
Can Gen. Rikichi Ando, wartime Japanese governor of Formosa and commanding general of Japanese troops on the island, swallowed poison in his jail cell here at midnight Friday and died in agony within a few minutes. Ando, his chief of staff, Lt. Gen. Hakusl Isayama, and 15 other Japanese had been brought to Shanghai Monday from Taihoku, Japan, for trial in connection with atrocities committed against Americans, British and Chinese em Formosa.
TOKIO, Feb. 19.- --W-- A Japanese in a United States army uniform--decorated like a Christmas tree -- stepped grandly off a train today. He had startled fellow passengers with tales of weird flights in '罈 rocket ship at the Kanoya air base. He was, he said with an elegant flourish, Captain Robert Jones - the army's most daring test pilot. He was dressed for the part. Loops of gold braid adorned both shoulders. Air force service patches blossomed on his sleeves. Two rows of vari colored ribbons illuminated his chest. Upon his jaunty cap were two circles of officer's braid and silver bars. But a United States army chaplain, A.D. Mann, lifted an eyebrow, and telephoned ahead. Awaiting the super pilot's triumphant arrival were two frowning MPs. They booked him for impersonating an officer. The rocket pilot extraordinarj admitted then he was Takeshi Takeshima--just an unemployed cooks helper from the Itami Air Base, near Osaka.
TAIPEI (AP) The crew of a U.S. military aerial refueling plane overpowered and disarmed a young Chinese who apparently was attempting to hijack their jet today, a U.S. spokesman said. The 17-year-old boy, who was carrying a shotgun, penetrated security patrols at Tainan Air Base near Tainan City in southern Taiwan. He boarded the KC-135 refueling tanker in darkness this morning, the spokesman said. He was turned over to Chinese authorities, the spoksman added.
Schenectady, March 28 (JP) - The pilot of the new army air forces Lockheed P-80 propellerless fighter plane sits in relative comfort, even in subzero temperatures, without heavy clothing, as the most powerful jet aircraft engine in the world warms his pressurized cabin. General Electric Co, officials disclosed yesterday that warm air flpws from the impeller-compressor of the jet engine into the enclosed cabin, where "pressurization" enables the pilot to breathe normally at altitudes of six miles and more without an oxygen mask.
The Navy wants lasers to shoot down drones and missiles, but its ships lack the power to fire them
2019/12/05
Unfortunately, this power management issue will only become more pronounced as the Navy develops even more powerful and power-hungry lasers over the next several years. The HELIOS system is only 60 kW, and the Navy wants to ramp up the power to 300 kW on future lasers so that they can burn through the nose cones of enemy cruise missiles, the report said.
The nose cones on supersonic cruise missiles, reinforced to survive the heat of friction with the air, make those missiles largely immune to dead-on laser strikes in the 60 kW to 150kW range, the report said.
>A few years ago, the Society of Experimental Test Pilots ran a flight test comparison of the F6F-5, FG-1D (Goodyear F4U), P-47D-40 and P-51D. Chief test pilot was John Ellis of Kal-Aero. Other pilots also participated.
>AIR-TO-AIR TRACKING 210 KIAS at 10,000 ft. (straight & level into a 3g turn to the left building to 4g followed by a hard reversal into a 4g right turn.) FG-1 best, followed by P-47, F6F and, trailing badly, the P-51. Lateral corrections in the P-51 were difficult thanks to the very high stick forces.
The Lockheed Martin X-59 QueSST ("Quiet Supersonic Transport") is an American experimental supersonic aircraft being developed at Skunk Works for NASA's Low-Boom Flight Demonstrator program.[3] Preliminary design started in February 2016, with the X-59 scheduled for delivery in late 2021 for flight tests from 2022. It is expected to cruise at Mach 1.42 (1,510 km/h; 937 mph) and 55,000 ft (16,800 m), creating a low 75 Perceived Level decibel (PLdB) thump to evaluate supersonic transport acceptability.
