Ahh, those were the days! NWI-LBA/HUY-EDI-ABZ, no autopilot, no APU..but we did get hot brekkies. (glad to see Eastern are still serving those nice folk from the East coast).
We had no problem with the pre arranged practice intercepts, it was when they sneeked up on us without warning we got a bit worried.
BTW BOAC the last word in my post above was NOT directed at you.
