I had no problem with the glass dome (Helicopters and Jets have them) but in the fact it didn't have a metal "Frame" at the corners. Look at the old Korean War Bell "Bubble" helicopters" and then look at the Apache Cockpit. I think if the Hiss had a metal frame along the plexiglass, it would have been ok. But for a Tank (which is usually the target of larger caliber Ordance than a helo or plane) straight Plexiglass is NOT a good idea.

And I think the NEW hiss would benefit from a small slit in the cockpit. Yeah, new generation parascopes are cool, but like all electronics, they suffer from ONE fundamantal design flaw: THEY RELY ON POWER! One Jolting hit to a Hiss could probably knock the power out or at least damage the electronics enough to put the driver in the dark!
