Trim Stab
I went solo in a jet aircraft with retractable undercarriage at the tender age of 19 with around 50 hours total flying under my belt, as did many others at the time (don't get too jealous).
Because of that small amount of experience, the RAF's risk mitigation was to stick a caravan at the end of the runway - an insurance policy if you like against Mr. Cockup knocking at the door. Guess what? It worked and may have saved a few aircraft and crew from being mashed.
If you have a problem with that, then I'd seriously question your attitude towards flight safety.
