No it's not. It's an appeal to the irrationality of the low-information types.
There is no evidence Hamas has the type of rockets that can be used to shoot down airplanes. If they did, they'd have used them against Israeli military aircraft by now. If they did have MANPADs, they'd have to infiltrate Israel to get close enough to Ben Gurion to use them. Even if they had the system the Ukrainian rebels used to shoot down MH17, flights coming from the north would be out of range from Gaza.
