Hypersonic Speed and Hindering Terrain

[Beyond Batman]

Does Falsh ignore the effects of hindering terrain? Does he get stuck in it? Hypersonic speed mentions never having to roll to break away... but what about hindering terrain?

One more question, do hovering characters have to roll to break away from either grounded or other hovering opponents?

[HeroComplex]

Flash is affected by hindering terrain just the same as any other non-flying figure.

Hovering characters have to breakaway from any adjacent opposing figures unless they have a power (such as Phasing) which allows them to ignore other figures.
