But while I was there, I saw this really wild clip of a Pan Am 747 tail strike (right click to save or jsut click to view):

Can anyone tell me about this incident? Does anyone know the story behind it or anything?

Thanks,

Could it be a early 747 used for testing on behalf of the certification?? If you look at the top of the tail, there is a sensor (I guess) hanging wired to the tail, probably for registration, so I guess this is test flight...

Kind regards,

Jeroen

Looks like a test to me.. there's something attatched to the underside of the tail, and attatched to the top of the tail fin. Maybe minimum unstick speed test?

I think it was at SFO in the early 70s. Hit the runway light posts. I will do more checking on this incident.

The fact that there is a piece of instrumentation trailing off the end of the vertical stabilizer tells me that this was still Boeing's aircraft when the footage was shot, and as such, was probably a "Vmu" test where they -intentionally- drag the tail to see at what speed the aircraft will fly itself off. The aircraft in question was not yet in passenger service.

Definitely a certification test. They attached a huge piece of wood to the aircraft and deliberately dragged the tail to determine Vmu as someone already mentioned. The 777 had a similar test when it was being certified.

I see the A340-600 at ATL every day. I freaks me out every time that I see her as I think for sure that there will be a tailstrike. Amazing!!

That was N747PA. It was 747 #2 during the 747 testing phase, wearing full Pan Am colors. Yes it was the VMU test. I have a different angle of the aircraft doing this test on a DVD. Pretty neat  Wink/being sarcastic


Caution wake turbulence, you are following a heavy jet.
