Plummeting out of the sky there mate! Was it close to bar closing time?
Interesting stuff on yer website.
No it was on a test flight to return the 747-300 to the owners. (Finished doing the Garuda Hajj, handing it back to Pratt & Whitney Aircraft Leasing)
One of the tests was to check the Vmo & Mmo clackers.
Here's Mmo.
Fun!
