Yes, but not for long. This is probably the stupidest lost comm story you'll ever hear. I was on a stage check focusing on en route IFR operations. It was night and we were flying from ASH to BDL
in a C-172R.
We were climbing out through a thin BKN layer at maybe 4000' and talking to Boston Center, when me and the instructor started to hear this static noise in our headsets. We could talk but not hear each other over it. It stopped and started several times, and this went on for 5 minutes. A few times we asked center if they could hear us and they told us to stop talking altogether and the noise continued, blocking their frequency. While it was on, sometimes I heard a click. After about five minutes that felt like a lot more than that, I realized what it was when I heard the click as my instructor moved his foot a little bit. The handheld mic was laying on the floor and he was stepping on it! He hung it up and that was the end of the problem! We were about ready to go through what we'd to when reaching BDL
without radio. Fortunately I noticed that stupid mic on the floor. We could have found a hole and landed somewhere VFR had it been a real comm failure or we had not noticed the mic.
