Tuner Aircraft Mk III

[Rosevidney1]

Designed by the Marconi firm. Any idea how long the type remained in service? It reputedly allowed clear speech for about 20 miles and was used to correct artillery gunfire. The airman ground operator was based in each Battery. Over 500 RAF airmen were killed doing that task in the period April to November 1918.

We've got more of this [COLOR=left=] rubbish, which has happened to me.

Does anyone know why it happens ?

I presume it's supposed to be a photo but not on my machine.
