Seeing any beta previews that weren’t published by Mr. Randazzo himself is a very uncommon thing for PMDG, but a couple of days ago one of the beta testers for the 747 V3 posted a few on AVSIM!
Problem was, he hosted them through Photobucket and they were down for maintenance for an unbelievable amount of time (you should see the comments on their social media). But finally the site came back up and the previews were back on AVSIM.
