I flew professionally for the better part of half a century and I would find it hard to find a type of aircraft that I have flown that did NOT have speed tape applied at some time or other.
Certainly, covering the sealant on a windscreen whilst it cured was a very common one. Covering bird strike damage or sealing a panel when a fastener had gone were others.
I will tell you one thing, speed tape does not come cheap. It litterally WILL stick sh*t to a blanket.
If you are ever lucky enough to get a roll, take it home and give it to your wife next time she wants to wax her legs.
She will tell you how good it is!
