EL AL 747 LHR yesterday

All
On my daily commute between Windsor & Luton, I get very used to the comings & goings at both my 'local' airports. However, yesterday evening on my return around 16:40, I think I saw a EL AL (?) 747 abort it's landing at LHR & climb really steeply away to effect a go-around.
I know from reading these forums that it is not an uncommon occurrence, but can anyone shed some more light on it, please ?
thanks

There could be many reasons for this routine procedure. Most common is that the aircraft ahead did not clear the runway in time. Whether someone will give you a precise reason remains to be seen...

There are typically about 550 go-arounds per year at Heathrow. I've heard it said that if the figure was lower then it would show that the controllers aren't doing their job properly

It's always worth looking at them on the WebTrak replay. On the evening of last December 15th there were 3 consecutive aircraft sent around on 09L, which is very unusual, though alas they have now scrolled off the end of WebTrak's 3 months' history.

Webtrak ? Is that still going ? Have you tried the later Aircraft trackers such as Casper or Planefinder.net, they have replays up to a year.

If you're looking for accurate arrival and departure tracks for 100% of LHR movements, neither Casper nor PlaneFinder will give you that. They can't track aircraft that don't have ADS-B (bmi Embraers, for example) and they can't accurately track aircraft with inertial-based navigation systems such as Lufthansa B735s.

WebTrak, on the other hand, captures 99.9% of movements. It also displays accurate heights, which the aforementioned systems don't.

The normal reason is that the aircraft does not have ADS-B - only Mode-S. A lot of regional aircraft are not ADS-B equipped. However, no guarantee this is the actual reaon - just a possibility.

You are correct, very few Embraers are so equipped.
