If the Aeros link is to show an Immelmann I think you will find it is wrong as the manouver shown in the sequence appears to be a roll off the top.
Many think of the half Cuban as correct for the origional Immelmann but in all probability it was more of a rudder lead wing over.

Essentially it was 'invented' by Herr Immelman to give him an advantage in a fight. The first section is get sufficient speed and then a climbing half turn to a roll off the top.
This link is even better because the graphics are animated. Its performance was actually a bit dangerous when you were climbing. You will note why.

This is actually the same link as I posted - if you look further down though it gives a description of the origional manouver that is not a roll off the top.
another link that shows this better is
http://spandau.250x.com/acm/wingover.zip
although described on the clip as a wingover the ACM site it comes from says:-
My understanding was that when invented the idea was to give two attacking passes, one on the first dive and the second on the return - this would not be possible with a simple roll off the top, also as said it would be very difficult to roll off the top with the Eindecker

With appologies to the thread drifters and their undoubtedly entertaining aeros the Defacation roll was spotted beautifully performed by the private owner of a pristine beautiful black P51 at an Everglades lake Okeechobee Hick airshow event held just after the Florida Airshow at Lauderdale Exec in 1968 starring Bob Hoover who had wowed the crowd in both the P51 and Twin Shrike Commander.
The budding P51 Tyro boosted and inspired by his hero, took off and on rotation sucked up undercarriage and began his roll. Once inverted he then sagged to within inches of the ground. In front of the now breathless crowd the inverted P51 tore grass all the way to perimeter hedge where it lifted partialy over leaving a prop shaped gap in hedge and continued with rapidly dissapearing Merlin noise but no sounds of rending metal and igniting high octane.
Sound diminished into distance where a few miles away a small dot could be seen slowly climbing still inverted. At approx 5,000' fighter rapidly rolls to level flight, slow turn back, RTB, landing(s) taxii to tower.
Figure of pilot seen climbing out and hastily waddling his way to 'gents' . Reverent silence from crowd at the brilliant demo of how not to roll, how to attract a miracle, and how to demonstrate the perfect Defacation Roll.

My apologies IH, I didn't notice. You are probably correct of course. Never flew the Eindecker but the one at Rhinebeck gave a good impression of the manouvre. But in battle I go along with the fact that it is dangerous - in that you were likely to be shot down - on the way up!
And Paterbrat, that is just the effect I imagine it can have.!

Paterbrat, that would also known in the Everglades as the Bog Roll... a very close relative of BEagle's Toilet Roll of course.
He wasn't Canadian perchance was he...?
