Is there any chance of finding this on DVD or VHS?
I did find it on youtube
No problem....it was released by Warner Home Video sometimes in the late '80s with another similar Irwin Allen made-for-tv disaster film, "Flood!". Try ebay or one of those other bidding websites.share
This film is available as an MOD DVD-R from Warner Archive.
