Ok....the "zero experience" quip was uncalled for but I stand by my having observed gear down landings.
I've seen two gear up landings as an adult on concrete under controlled circumstances and the sliding was quite long and more than a few as a child.
I witnessed plenty of belly landings at NAS Lemoore as a kid in the 1960s as airport operations were a bit slack because my friends and I could watch them practice carrier traps on the arresting gear only a few hundred yards away as we ran all over that base.
I saw an unintentional gear up landing years later while I was standing with the president of A.O.P.A after winning a contest among employees on aviation proceedure as the only person who answered every single question correctly on a quiz. (it had to do with flashing red light in the segmented circle and nobody else got that question right)
He later invited me to his office a few times during lunch to play a new game called "strike eagle".
Strangely, I see no mention of the incident but I remember the president spotting a plane on short final and joking with the avemco employees among us at lunch that they might have some work to do if the guy didn't lower his gear soon.
The guy never lowered his gear........just plain forgot.
The sliding was quite long.
His plane had a small playboy logo on the tail and we were able to walk right up and greet the pilot before any emergency trucks had even started thier engines.
No fuel leaks and I had to lean in and turn off the master switch and magnetos because the shaken pilot had forgotten them as well.
I saw a couple of others at manassas airport including a mooney that landed gear up accidently, struck the prop, added power, and went around for another shot at landing....this time with gear down.
These guys weren't landing at 180mph in planes with high wing loading at high speeds but rather less than half that, but for some reason, planes stop a whole lot faster in aces high to the point that many here don't ever bother with gear down landings unless they are rearming for the simple fact that they are only interested in getting
stopped so they can get another plane as soon as possible.
Here is a video that illustrates the distances to which I am referring.
