For a few years now, the B2 Bomber has flew by the Rose Parade prior to it’s start. I just noticed something: how do they get shots of the bomber in flight from above? Is there another plane following it? It doesn’t look like it’s shot from inside another plane (no lens glare from being shot through a window) and helicopters and buildings wouldn’t be able to follow the B2 in flight. Is it shot from a plane with an open window? Some type of camera drone?
Blimp.
Watch out, Scylla!
I don’t know the answer to the OP, but Clay Lacy Aviation is in Van Nuys and they offer aerial cinematography/videography.
Doh! The blimp! :smack: Forgot those existed. Ever slow and combustible, yet the gentlemenly way of travel, until the Nazi’s discovered a fetish for them…
I couldn’t tell from the TV view of the plane.
How low was the flyover? Was it just a speck in the sky to the parade spectators?
Couldn’t it go really low or would the mountains around Pasadena make it too dangerous?
It flies fairly low over the parade route, if I had to guess 1,000-2,000 feet above the ground. Very visible from the parade route.
The mountains are not really an issue as Colorado Blvd (the parade route) runs parallel to them.
(Several companies have them around here, not just Goodyear.) Helium? Combustible? 
Oh, whoosh, I guess. But they are slow. Gentlemanly, couldn’t say from personal experience, but doubtlessly so.
Yes from another plane pacing the target. You over estimate the impact of the canopy on the picture.
With a large diameter lens correctly focused, the intervening canopy/window glass will be invisible.
Nearly all helium in those days was extracted in the USA, which refused to sell any to Germany post WWI as demanded by the Versailles Treaty. The Germans instead used to only other available gas: hydrogen.
News helicopter?
Another nitpick. Germany had dirigibles, not blimps.
When the pros shoot aerial, they don’t just send a guy up with a camera to sit in the passenger’s seat. They use an aerial camera mount, attached to the outside of the plane or helicopter. It’s remotely controlled by an operator inside the plane, who can change its pan, tilt, and roll.
