aviation radio history

I'm interested in researching the development of the use of radios in aircraft, especially the early use of radios in observation aircraft that was in use around 1914 and the development of this technology for military use. Any information would be appreciated.

Hello Dan

This is all I have at the moment.

First radio signal 1892 (distance 1320ft) sent by Sir William Preece.
Then Marconi in 1895 (1 mile), 1901 (3000 miles!!!!!!!)
First ground signal received in the air (by British balloon 1905)
The first radio in a German Zepplin (LZ 6 in 1909)
First radio signal between aeroplane and ground in USA (1910)
First British aircraft fitted with a radio 1912.
By 1914 signals received over a distance of 100 miles.
First British radio message between aircraft 1914 at a range of 10 miles.

Try to find more,
Best regards

"Enemy troop movements observed, co-ordinates to follow, but first a word from our sponsor."

The first wireless sets used in RFC observation aircraft were very heavy (75 lbs. or more), and their use precluded the carrying of an observer. This, needless to say, often put a crimp in artillery spotting (and may be a reason why the inherently stable BE-2 was retained in production). By 1915 and the Battle of Loos, more compact wireless sets had been developed. (Wireless aerials were loops of wire that were unspooled once the aircraft were over the target area. I've seen a number of references to aerials becoming stuck while unspooled, and having to be cut.)
