Yes, that's possible, too. The 747 was about 1:43 behind the 777 when they overflew the Duke of Wellington (as was), with a GS about 10 knots faster.
The GA was initiated at 12:25:41, about 1.7 nm from the threshold. Unfortunately you can't tell from WebTrak how long an aircraft has taken to clear the runway.
