There may be no practical, affordable way to to this; but there might be; so I'll ask ? Circa 25,000 to 35,000 feet aloft, over my home; I see many large airline aircraft. They are especially visable at sunset; and at night, if lit by on- board navigation strobe-lights. First, does digital vs. film matter? I only own an old Nikon FA. The primary question is: how do I get the flash of the on- aircraft strobes aloft, to trigger the exposure in my camera ? Jim Miller , Southport,N.C.
