Its caused by the massive airflow over the lettering.
The stickers obviously have not been edge sealed properly, allowing air to get underneath and at 400mph those stickers can’t withstand that force and rip away.
Just can’t understand why they allow this to happen, it must cost them time out to get it redone properly.
Lets face it, the poor 600 looks worse than the Ryanair/Hertz logo jet now doesn’t it! :rolleyes:
