I'm a licensed Aircraft Mechanic & Inspector with twenty five-plus years in the field. I've had a varied career so far, with time spent in the sheetmetal, mechanic, and inspection specialties. Most of my time is on heavy Boeing and McDonnell Douglas aircraft, of the passenger, cargo, and experimental type. This career isn't for everyone, but I enjoy it.
Please do NOT ask me to troubleshoot problems with your airplane, that is not what this Q&A is for.
Regular aircraft cannot fly along upside down like in an airshow. The reason for this is that the fuel and oil systems are designed for a one Gee environment. The fuel pickups in the tanks are on the bottom of the tanks in the lowest corners. The oil tanks on the engines feed from the bottom of the tank. So if you go upside down, those oil and fuel pickups will suck air. You can roll an airplane as long as you maintain at least one Gee. As the famous Boeing test pilot did when the Boeing 707 was having it's debut. For a very skilled pilot, such a maneuver would be possible. Airplanes that you see performing upside down, have either been designed from the start to do such things, or have been modified.

There aren't any additional hurdles for your friend, as far as obtaining his mechanic's licenses from the FAA. Nor in keeping them; as long as he stays sober on the job.
Finding a job with an employer after he gets his licenses, is another matter entirely. If he doesn't have a driver's license, due to it being revoked; then not only will he have the problem everyone has in that situation, of begging rides to work. But he will have the additional issue of not being able to drive any company owned vehicles on the airport or facility. That usually means ramp vehicles, forklifts, etc. They almost always want driver's licenses for that.
Also, lots of airport security screenings, will do the ten year background checks. And won't always be willing to issue ramp access badges to someone with recent legal trouble like that.
Many companies have government contracts; and do those background checks as well. And wouldn't be able to use someone with extensive legal issues on any government type work.
My advice to him would be to hunt around until he finds a place that is willing to take him on; and keep his record clean while he gets experience on the job. Then, later on he can shoot for a better position somewhere.
For what it's worth: The aviation maintenance 'club' is often not a dry one. Drinking after work, and partying is the norm. Long hours, and often frustrating work feed it as well.
I won't play nanny to him. But it might be a tough road for a few years for him. He can do it though, if this is really what he wants to do for the rest of his life.

I'm not terribly familiar with what you have there. My specialty lies more in large turbine aircraft, size DC-9 and up.
But, for my two cents worth: I guess it would depend on where the engine was stored. If it was outside, or somewhere damp, then sure, it would probably have corroded a little inside the cylinders maybe. But, do you know what the compression of the engine was before he took them out ten weeks ago?
Not to defend the guy. In my opinion, and as standard practice; you should ALWAYS plug holes just like those. Just to keep dust an dirt out of them. To say nothing about bugs (who may build things in there), and other foreign objects.
I really couldn't guess if that is what caused the low compression readings. But, if they really were left wide open for ten weeks, it certainly didn't help anything.
Sorry to hear of your difficulties. I hope you can get things sorted out without too much trouble.

That sounds like a question for Adam and Jamie over at Mythbusters!
I don't really know.
After the initial air pressure equaliziation, which could be quite turbulent I suppose; you'd still have the air rushing along outside the open hatch. That would create some suction, courtesy of Bernouli's principle.
I guess as long as you stayed away from it, and were belted in, it might be all right.
A more immediate concern would be bringing the aircraft down to an altitude that had enough oxygen for humans to live.
And further: Opening an emergency hatch would be a Herculian effort for sure. All the emergency exits I've seen, are plug type hatches. Which means that whomever 'ripped' it out; would be fighting against the higher air pressure of the inside of the airplane, versus the outside air.
Those few psi don't sound like much, but it adds up to a lot of force holding that plug type hatch in place, even without a latch holding it.

Rap Promoter / Manager
Do venues you rent express concern about a higher risk of violence because it's a rap concert?
Police Officer
Can I become a cop if I have misdemeanors on my record?
Mailman (City Letter Carrier)
Is there a big difference in the amount of mail you deliver today from 5-10 years ago?
I would speculate that there are more contrails in the sky over Crimea, because it is a very interesting place, and there are planes taking lots of pictures of what is going on. That, and people leaving, on airplanes.
I don't reckon that they were chemtrails. I've never seen any evidence of chemical spraying devices on any aircraft I've ever worked on.
As far as to the existence of said chemtrails. We should look for the simplest explanation.
Is what we see streaming out behind aircraft at altitude, a condensation of water vapor around the warm engine exhaust?
Or is it a worldwide government plot, to plant mind control chemicals in aircraft (and somehow keep that all secret) to be sprayed into the atmosphere?
My money is on the simple condensation.

Yes. It is easy to find a job. IF you have your A&P license, AND you are willing to go to where the jobs are.
There are most often jobs available, not necessarily in your immediate area, and you might have to go with a contracting company. But there are jobs.
If you don't have your license, or you aren't willing to move at least yourself to wherever the work is; then there might be a harder time finding a job.

Currently, as an inspector in an engine shop, my tools consist of what I carry on my belt: A good flashlight, a leatherman, a mirror, a blue pen, black pen, and red grease pencil.
Our shop cabinet has numerous precision measuring devices. Calipers, micrometers, depth guages, etc. All a mix of Starrett, and Mitutoyo brands.
We also have two GE borescope kits, which are simply marvelous.
When I was a mechanic, I had a Stanley Vidmar toolbox, which I judge to be the sturdiest for the money. With a mix of Craftsman, Mac, and Snap-On tools inside.
Basically consisting of what you'd imagine to be in a mechanic's box. Screwdrivers, wrenches, sockets, hammers, punches; with several different variations of each.
Also: Don't underestimate the value of keeping a 'cheap' set of wrenches and sockets in your box. They are used to make 'special' tools (bending, cutting, etc) to reach difficult areas. That way you don't have to wreck your good brand tools.
I can't exaggerate how much I love my Snap-On Ratcheting screwdriver. Get one with the 'old fashioned' hard plastic handle, as the newer one with the rubberized inserts will get eaten by the hydraulic fluid.
Start off with the basic tool list your workplace will give you. And just build it intelligently from there. Buy quality when you can. But Craftsman works just fine, don't be a tool snob.
There seems to be an almost infinite number of specialized tools and fixtures that each particular aircraft you work on will need. Usually, the company you work for will buy or rent those for your use. Occasionally, you will find yourself doing one certain job so often, that it makes sense for you to buy, or make it for yourself. But you won't know that, until you do.
