Chicken flight - Tradução em português

Hello everyone.

Alguém conhece ou poderia me esclarecer qual o significado da expressão "chicken flight" dentro do contexto abaixo?

Many have now lost faith in the idea that their country was headed for orbit and diagnosed just another voo de galinha (chicken flight), as they dubbed previous short-lived economic spurts.
