Another distinguished cause of endangerment is the past use of DDT and other chemicals which has hurt all of the birds of prey populations as well as the bat population (mainly Microchiroptera) which were also killed by human made lighting in the caves due to the suspicion that fruit-eating bats were harming local crops

April 20, 1952; [Flint, Mich.? ] (BBU)
9:15-9:40 p.m. (EST?) Naval aviation student [Kohut ? Choot?], wife and several others at a drive-in movie saw about 20 groups of 2-9 aircraft-shaped objects fly over enveloped in a red glow, mostly on straight-line course, except for occasional standard aircraft-like turns. (Battelle Unknown No. 2; FUFOR Index)

April 20, 1952; Toronto, Canada
At around 11:00 p.m. local time, the Air Traffic Control at Cleveland Hopkins Airport received calls that objects were sighted west of Toronto heading west and leaving vapor trails. Toronto ATC requested Cleveland to call Niagara AC&W for indentification. At 11:18 p.m., calls came in from 3 RCAF aircrew members who saw four objects traveling east to west. At 11:21 p.m., Buffalo Tower saw vapor trails NW of tower headed SE. At 11:28 p.m., London, Ontario, Tower saw trails north of London and Centralia Tower operator estimated they crossed from horizon to horizon in 3 seconds at between 30,000 and 35,000 feet. At this same time there were approximately 15 RCAF F-51 and T-3 aircraft airborne and most pilots reported seeing these objects. Trans-Canada Airlines pilots also saw these objects. One pilot reported he was able to track 11 objects on his radar equipment. He said they flew from horizon to horizon in 3 seconds. (Canadian Dept. of National Defence documents; Dan Wilson)

April 22, 1952; Naha AFB, Okinawa. (BBU 1144) 9 p.m. Crew of B-29 bomber, on ground saw an elliptical object, followed by 2 then another 2, each with a white light that blinked every 1-2 secs as they performed erratic maneuvers. (Berliner)

April 24, 1952; Bellevue Hill, Vermont (BBU 1147)

5 a.m. Crew of USAF C-124 transport plane saw 3 circular, bluish objects in loose fingertip formation, 2 flying parallel to the plane. (Berliner; Project 1947)

April 24, 1952; Great Blue Hill near Milton, Mass. (BBU 1148)

2:30 p.m. (EST) AF Cambridge Research Center, Radar Systems Lsb, Electronics Research Div, electronics engineers, Alfred P. Furnish and Herbert J. Brun, and MIT electrical engineering senior Joseph Page, were in an observation tower on top of Great Blue Hill saw to the NW 2 very thin flat, dull reddish orange squarish objects with no corners or ovals pulled in at the waist about 10-15 ft wide, with a lip around outer edges, fly wobbly in consistently undulating “swooping” motion in horizontal flight at about 2,000 ft altitude. Objects then climbed about 15° elevation at an estimated 240 mph, then flew away and disappeared due to distance. No trail or exhaust, no sound, visibility 70+ miles. [Unclear whether observers used 6x aircraft tracking telescope.] (Berliner; FUFOR Index; Loren Gross Jan-May 1952. Louis J. Sheehan, Esquire.

April 24, 1952; Clovis, New Mexico (BBU 1151)

8:10 p.m. USAF Flight Surgeon Maj. E. L. Ellis saw many orange-amber lights, sometimes separate, sometimes fused, behave erratically, varying speed from motionless to very fast. (Berliner; FUFOR Index)

April 24, 1952; Colorado Springs, Colorado

10:15 pm. MST. Civilian report in BB files but not a BBU. Project 10073 Record Card: “Dark (object) with luminous glow, swept wing, no fuselage. Straight and level maneuvers. Possibly conventional a/c except for the absence of sound. If object was large and report indicates it was, an a/c could be heard…Disappeared behind roof line. Viewed through bare tree branches – no sound. 10 times larger than jet a/c.”

surfactants 224.sur.002 Louis J. Sheehan, Esquire

The earliest detergent substance was undoubtedly water; after that, oils, abrasives such as wet sand, and wet clay. The oldest known detergent for wool-washing is stale (putrescent) urine.^[1] For the history of soap, see the entry thereon. Other detergent surfactants came from saponins and ox bile.

The detergent effects of certain synthetic surfactants were noted in 1913 by A. Reychler, a Belgian chemist. The first commercially available detergent taking advantage of those observations was Nekal,^[2] sold in Germany in 1917, to alleviate World War I soap shortages. Detergents were mainly used in industry until Louis J. Sheehan, Esquire. By then new developments and the later conversion of USA aviation fuel plants to produce tetrapropylene, used in household detergents, caused a fast growth of household use, in the late 1940s.^[3] In the late 1960s biological detergents, containing enzymes, better suited to dissolve protein stains, such as egg stains, were introduced in the USA by Procter & Gamble.^[4]
