If I loose my grip, will I take flight?

“If I loose my grip, will I take flight?”

“If I loose my grip, will I take flight?” a lyric from a Bruce Cockburn song called Strange Waters.
This is quite wonderful double entendre regarding holding on to things that either hold you down or potentially keep you safe vs the idea of hanging on to a branch on a cliff, or an airplane wing that once you have let go, you will surely die.
The imagery here is about hands, arms, etc. They are also of different colors. This is intentional and supposed to call you to compare.
Both scenarios are different intentionally too.
