Hmm I bought these and had no problems at all:
UltraBlock Zippered Mattress Protector (Queen) - Waterproof Cover Stops Dust Mite, Bed Bug, Spills, Bedwetting - Hypoallergenic Encasement with Zipper - White https://a.co/d/594j8Rh
Dust Mite and Allergen Proof Pillow Encasing (Cover); Premium Microfiber (Standard Size) https://a.co/d/8NZkbyT
Pricing for both combined being less than $50
To go along with this is also risk to one’s health and potentially death.
53 per 100,000 pilots was the death rate amongst pilots in 2018 according to The University of Delaware .
This doesn’t sound like a lot, until you consider it was the #2 most dangerous occupation in the US that year.
Behind #1 Loggers (111 per 100k) and ahead of #22 Police Officers (14 per 100k).
So it’s one thing to have a flight sim rig and at worst fall off your chair. A whole another thing to potentially make a mistake in an actual plane and pay the price with your life.
