Yesterday, I actually saw an AI 787X at EGLL (ETD12 to Doha) I couldn’t believe it! It was default livery but when I saw an AI with the label ‘Boeing’ as I approached 27R, I thought it couldn’t be… And yet it was. It was taxing to the RWY hold point just as I crossed the threshold, so cool. Its part of the sim that has lots of potential, just have to be patient, it will happen!
