Why stow away in a wheel well? No windows, no life support systems, no sound proofing, and gear operated by a hydraulic system designed to put that gear in the well despite a human stowaway. I don’t even know if there is room in there for a human. I would seriously doubt it as extra space means weight and planes are built for the least weight possible. If he wasn’t crushed by the gear, the hypoxia would have done the job.
Movie stars do it all the time. Heck, I've even seen them ride on the outside of a jet, and their hair doesn't even get out of place.
: )
There’s plenty of room. See post 28.
