If you want to get the attention of a pilot you might want to try this. In the 1970s I lived in an apartment adjacent to the North Runway at LAX. This runway was used exclusively by the heavy iron (747s, L 1011s and DC-10s). Some of the airlines had operational procedures that kept them on the runway until the last minute to build up speed and when they lifted off the runway they would climb NOE over a large hill with a Nike Base on the top. This was difficult enough in the daylight but at night it was just asking for an accident.
It seems that some of the local youth (or should that be plural yeeth) had obtained a block of magnesium along with several smaller pieces. The placed it in a field adjacent to the runway at about 9-10:00 PM and set the magnesium alight. I can only imagine what the pilots thought when they lost their night vision capability but it was obvious that those airlines that had the delayed lift off were in a lot of problems as they could not see Nike hill nor could they see where they were in relation to the runway length. The cops and the LAX fire department were on it in about five minutes and put the fire out but in the meantime the pilots and controllers were going crazy.
