It could be the 747 that routes MAN-GLA then onwards to MCO. This would continue straight ahead for a while off 05L then turn left to POL a lot later than the WAL departures do.

After getting some more information, it does seem that it was a departure that was having a bit of difficulty climbing- nice to know!
I wouldn't have thought it was 'having difficulty' climbing. You make it sound like it was in trouble! It was probably a 747 full of holiday passengers and fuel for the transatlantic trip so very heavy. 4 engined heavies don't climb as quickly as the twins so although it may be climbing slower than a B767 for example, it certainly wouldn't have been having 'difficulty'! You should see an A340 climb, especially at the higher levels
