Wooden aircraft are not inherently invisible to radar. Swordfish could disappear into radar clutter because it flew low and slowly. Mosquito's speed could prevent interception, which helped perpetuate the same myth even though the difficulty was different. Dragon tentatively suggests that non-uniform material density and surface could scatter returns for early radar receivers at range, while explicitly saying he does not know whether this is true. That proposed effect remains unresolved.

The myth of radar-invisible wooden aircraft
Radar clutter hindered detection of Swordfish, while speed hindered interception of Mosquito; both effects helped sustain a myth about wooden aircraft.
