You're reaching, buddy. What created Cap was the serum. The machines were only used to Stabilize the process. Erskine came up with all of that himself, it wasn't Howard Stark. He used it to create Red Skull for HYDRA *before* creating Steve Rogers. It didn't work perfectly on Skull because of who he was- a corrupt individual would result in a corrupt process which is WHY Steve Rogers got chosen. Other than his physical appearance, Red Skull was an exact match for Rogers in combat.
Your excuses are getting pretty old. That's obviously a modern intercom/security setup, designed to use WiFi/RFID or similar to gain access. They are extremely common today, but did not exist in the 80s or 90s. Howard Stark didn't invent those things or anything similar to it- he worked on military equipment, bombs, and similar.
The most likely explanation, given the van, and the security setup is that this is modern footage- not that Howard Stark invented Bluetooth and didn't tell anybody about it.
This is the last time I'm addressing you BTW. no need to respond.
edit: also, this is the security footage from 1991 when Winter Soldier killed Howard Stark outside of whatever facility he was heading to with his serum.
Why would random security footage from a warehouse in the 1980s have drastically better image quality and fidelity than footage from a secure facility in 1991?
Again, the camera tech to make that video of scott didn't exist in the 1980s, even for stark. Game, Set, Match.
