The 1966 Palomares B-52 crash, or the Palomares incident, occurred on 17 January 1966, when a B-52G bomber of the United States Air Force's Strategic Air Command collided with a KC-135 tanker during mid-air refuelling at 31000 ft over the Mediterranean Sea, off the coast of Spain.

Challenger is a 1990 American disaster drama television film based on the events surrounding the Space Shuttle "Challenger" disaster.
 Its production was somewhat controversial as the families of the astronauts generally objected to it.
 The film concentrates on the safety inspections and arguments surrounding the O-rings that ultimately were blamed for the explosion of "Challenger".
 While doing this, it also aims to show the personal humanity of the seven crew members.
 Generally, the film supports the Space Shuttle program and the dedication of NASA personnel in general while criticizing NASA management.
Visa requirements for crew members are administrative entry restrictions imposed by the countries for the pilot or a member of the crew during a transit.
 The crew visas are associated with the request for permission to enter a country for a short duration and perform the predefined duties in the given areas, distinct from actual formal permission for an alien to enter and remain in the country.
 Validity of transit visas for crew members is usually limited by short terms such as several hours to 10 days depending on the size of the country and the circumstances.
 The visa policy for crew members is set by the country and applies to during the transit or to join the vessel.
 It is illegal for the crew members to perform repairs or similar work without work permits in port, or traveling in the waters.
 By law, only a few countries that offer a visa waiver program or do not issue a crew visa, but allow their entry for a limited time with mandatory clearance documents.
 Most of the countries permit crew members to travel within the Common Travel Area by carrying a passport or a national identity card.

 In 2003, Chawla was one of the seven crew members who died in the Space Shuttle "Columbia" disaster when the craft disintegrated during its re-entry into the Earth's atmosphere.
 Chawla is a recipient of the Congressional Space Medal of Honor.
