Near-Miss London Heathrow BA168 & Bangladesh BG017

Video includes ATC to Bangladesh aircraft It's not a good day when heathrow gives you a phone number to call. 20th Sept 2014 I was recording my new collection and came across this. I've had a quick look at FR24, what do you guys think? I think it wasn't as bad as 2 miles is still good room if they are almost going in the same direction but i don't know i'll have to have another look. near miss
