From 1938:
Pretty morbid, the fashion of the era seems to have been jumpers - I've seen several 'news photos' of such, they especially liked women in skirts...
On this page, details of the Big Bertha telephoto Graflex rig - 70cm Carl Zeiss f/5 triplet, weighing 25 lbs.
The article continues on about the equipment used:
the guys on ground all used 4x5 Speed Graphics with f/4.5 lenses
"One of the most remarkable shots made with this equipment ... with a No. 2 bulb as the body passed the 6th floor, with lens set at f/4.5 and 1/200 second. Enlargement of less than 20 per cent of the negative area yielded a spectacular print in spite of the fact that the distance covered by the flash bulb was close to 100 feet."
"Movie men had their troubles too. ,,, the actual jump was filmed with De Vry and Eymo hand cameras with 100 foot magazines loaded with Du Pont XL.... After dark lighting was by means of magnesium flares which burn for three minutes at close to 75,000 candlepower. Half a dozen of these flares will illuminate an area of more than 50 feet in depth. Normally 150-amp sunlight arcs would be used but in this case they were not approved by police."
