As a bochur in 770 there were certainly times during Tishrei when I felt like I was getting carried with the crowd without any control or had to push back to stop from getting crushed.
Certainly claustrophobic, though at the time I didn't feel in mortal peril. Then again, others felt the same way about Meron in the past. And from what I understand, nothing was particularly different or more crowded than in the past.
I felt the same way at the Kotel on Shavuos at netz 2 years ago.
Maybe in this post-Meron world we need to examine, fix, or enforce capacity limits on other crowded spaces to avoid a repeat of such a tragedy?
Where have you felt like it could be too crowded for safety?
