Several hours depending on the speed of the aircraft, the altitude and its weight.

The F4 Phantom II did over 1,500 mph. If you meant F14 that was a post Viet War jet called the F14 Tomcat.
Mercury emitted from burning coal can stay airborne for days to weeks, depending on various factors such as weather conditions, altitude, and location. It can travel long distances before eventually settling to the ground or water bodies, where it can accumulate in the environment.
Research suggests that flies can stay in the air for about one to two miles without rest. The average speed of a fly is about five miles per hour.

http://www.airlinecrew.net/vbulletin/showthread.php?p=1449726: If you are within a couple feet of an infected person who coughs or sneezes, you can breathe in the fine droplets. If you are farther away, you are less at risk for catching the virus that way. The sneezed/coughed droplets don't stay airborne for very long, but viruses can survive for quite a long time on surfaces, once the droplets fall. Hope this will help...
Birds can hover in place for short periods of time, but they typically need to move forward to stay airborne due to the way their wings generate lift.
Mach 2.34 (1,544mph)
F13 = {Shift Key}+F1 F14 = {Shift Key}+F2 F15 = {Shift Key}+F3 etc.
