The UK is well known for its links with aviation. The Indra Dhanush exercise with the Indian Airforce is one of those highlights.
In 2007 the Indian Airforce brought both Su-27 and Su-30MKI to RAF Waddington to combat the Tornado F3. RAF Waddington is very open at both ends of the runway and is perfect for photography (as long as you bring a small stepladder).
I made a daytrip by ferry from Rotterdam to Newcastle which turned out to be very succesful.
