I'm sure you're right. Still glad I avoided direct skin contact.

BTW, I see you're an airplane builder. I went through the process (a Pitts open cockpit single-seater). If I had to do it again I'd probably pick a Falco.

At the time, I was co-owner of an automatic door business. We had quite a few glass panes ('lites') from supermarket storefronts and built an extension to the barn to build the plane. When we were done, we just disassembled the structure. No issues with moving through a doorway, no need to rent a hangar (process took about a year and a half). We took all the vertical lites out (so 3 sides open) when we were applying 'dope' to the fabric. Those volatiles seemed toxic - and potentially explosive - so we froze.

I also see you taught anesthesia. We did a number of OR doors (sliders) as we could build for potentially explosive environments (hydraulic w remote pumps, pneumatic controls) and doors could break-away (turn into a hinged door) in either direction.
