The Battle of Los Angeles
                        
                        When? 1942
                        Where? Los Angeles, California
                        What happened? On the  night of 24 February 1942, not too long after the attack on Pearl  Harbor, air raid sirens rang out across Los Angeles. Thousands of people  witnessed searchlights around Los Angeles fixing on a target hovering  over the city, and the Coast Guard Anti-aircraft guns were ready to  fire. They assumed it was an attack from Japan – but they were wrong. To  this day, the Japanese claim they never attacked and there is no  wreckage or other evidence to say that they did. People inland started  to report seeing the large craft, or fleet, and Air Raid Wardens put the  city into blackout. Some witnesses describe the sighting as a  tremendous single object, crawling through the sky, whilst others say it  was a group of smaller objects. At 3.16am a barrage of AA shells began,  and the firing at the object continued throughout the night until the  blackout was lifted at 7.21am. Several buildings were damaged in the  firing and six people were killed – three by friendly fire and three  from stress caused by the attacks.
                        How was it explained?  The next morning the papers were filled with several different  explanations. Some reported that it was Japanese planes that were shot  down – though there was no evidence to say that this was the case. The  LA Times ran a front-page picture showing an image of an odd object  caught in the searchlights. The Government denounced the whole story,  calling it a false alarm caused by ‘war nerves’, however many witnesses  confirm that they believe what they saw was extra-terrestrial.
                        
                        The Belgian UFO Wave
                                                                           
                        When? 1989 - 1990
                        Where? Across Belgium
                        What happened? These  sightings began in 1989 but peaked with the events on 30/31 March 1990.  On that night several unknown objects were tracked by two Belgian  aircrafts and photographed. Additionally, they were witnessed by around  13,500 people with 2,600 filing official written statements detailing  what they saw. The general description of the sighting is of three  unusual lights, brighter than stars and changing colour, flying across  the sky towards the South-East of Brussels. Patrols of Belgian aircraft  were sent to investigate and try to track the lights, which had formed  into small triangles. They managed to obtain a radar lock onto the  unidentified crafts on three occasions, but their targets rapidly  accelerated each time before descending to ground level. The pilots  never made visual contact with the targets. The sudden changes in speed  of the unidentified crafts should have been fatal to their pilots.  Ground witnesses, the police and the pilots all give identical accounts  of this sighting.
                        How was it explained?  Many people are sceptical about these sightings, mainly because the only  photo to emerge from the wave turned out to be a hoax. A lot of people  explain the sightings as mass delusion, from misinformation spread by  the media and the UFO logical organisation. Others argue that they were  simply helicopters, their silence explained by a strong natural wind, or  other noise drowning their engine sound out. However, nothing has been  confirmed or verified, and the Belgian UFO Wave remains unexplained.
                        
                        The Lubbock Lights
                        When? August-September 1951
                        Where? Lubbock, Texas
                        What happened? On the  night of 25 August 1951 Dr. W.I. Robinson was standing in the back  garden of his home with two of his colleagues from the Texas  Technological College, Professor Ducker and Dr. Oberg. All of a sudden  all three men saw several lights fly across the sky, silently. They flew  across the whole horizon within a matter of seconds, and the same thing  happened again a few moments later. Between August and November  Professor Ducker claims to have seen 12 similar flights, and several of  his colleagues witnessed some as well. Hundreds of other non-scientists  claimed to have seen the lights too. On the evening of 30 August, Texas  Tech student, Carl Hart Jr. spotted the lights and was able to take five  successive photos of them with his 35-mm Kodak camera. He was paid $10  for the photos and they were printed in papers nationally. However, the  professors stated that these photos did not accurately portray the  lights they had been seeing. Carl photographed the lights flying in a V  formation – the professors had consistently seen them flying in a U  shape.
                        How was it explained?  Captain Edward J. Ruppelt, who would later become the first director of  Project Blue Book, was sent to Lubbock to investigate the lights. To  this day, an extraterrestrial explanation for the lights has never been  fully debunked, however, other possible explanations have been cited. It  was suggested that it was a group of Plover birds, shooting stars or  comet fragments – though none of these explanations ever really fit the  bill.
                        
                        The Chiles-Whitted Sighting
                        When? 24 July 1948
                        Where? Montgomery, Alabama
                        What happened?  This case was one of the very first UFO sightings reported by  commercial pilots. Whilst flying from Houston to Atlanta, pilots Chiles  and Whitted encountered a large, cigar-shaped craft flying close to  them, barely missing them at times. At one point, the object appeared to  stop abruptly before vanishing into thin air. The pilots agreed that it  was a long, thin craft, with two rows of windows that emitted a blueish  glow. It was moving really fast, leaving a trail of orange/red exhaust  in its wake. What makes this sighting more credible is that this  sighting wasn’t only reported by Chiles and Whitted.  Several witnesses  at an airbase in Georgia claim to have seen an identical object half an  hour before the pilots’ experience. Government officials were able to  rule out the possibility of it being a military or commercial flight as  there were no fitting flights scheduled at that time.
                        How was it explained? After  an investigation, government debunkers wrote the sighting off as an  illusion caused by temperature inversions, and later changed their minds  and claimed it was a meteor. However, as the description of the object  does not at all fit that of a meteor, this sighting is still classed as  ‘unexplained’.
