A flare or decoy flare is an aerial infrared countermeasure used by an aircraft to counter an infrared homing ("heat-seeking") surface-to-air missile or air-to-air missile. Flares are commonly composed of a pyrotechnic composition based on magnesium or another hot-burning metal, with burning temperature equal to or hotter than engine exhaust.
Very low IR transmission through liquid water and ice, which precludes all-weather operation. Even a few tens of micrometers of water on the lens, or in the atmosphere between the threat and the sensor, is sufficient to effectively blind both MWIR and LWIR sensors. Must compete with massive amounts of natural (sun) and man-made IR clutter.
In June 2014, the Canadian National Aerial Surveillance Program DHC-8M-100 aircraft mounted with infrared sensors was instrumental in the search for Justin Bourque, a fugitive who had killed three Royal Canadian Mounted Police members in Moncton. The plane's crew used its advanced heat-sensing camera to discover Bourque's heat signature in the ...

A hand ...
Amid growing anxieties surrounding reported drone sightings, the FBI has issued a warning against a new trend of pointing lasers at aircrafts.
An airborne sensor operator (aerial sensor operator, ASO, Aerial Remote Sensing Data Acquisition Specialist, Aerial Payload Operator, Police Tactical Flight Officer, Tactical Coordinator etc.) is the functional profession of gathering information from an airborne platform (Manned or Unmanned) and/or oversee mission management systems for academic, commercial, public safety or military remote ...
The Eiffel Tower in Paris, had an aerial lighthouse between 1947 and 1970, when the French aviation authority estimated that it was no longer needed to help aerial navigation, and set instead the standard warning lamps on top of the tower. In 2000 it was decided to uninstall the warning lamps and install again an aerial lighthouse visible by ...
