Around 1978 I saw an Aztec line up and go on 28R at Heathrow with a Pan Am 747 practically over the fence.
The 747 went round, moving to the left of the runway (ie closer to the central area), presumably so the First Officer could see where the Aztec was. The Aztec stayed low, from the Queens Building Roof I didn't see it much after it lifted off.
Didn't have an airband radio in those days so I've no idea how the conversation between the three parties went; I imagine it may have been a little tense!
