*These altitudes were achieved prior to the formation of the WRA2 and are generally accepted by the Water rocket community as former records. None of these flights carried an onboard camera so each had a weight advantage. Each of these altitudes was also achieved with only a single flight.

**Team or personal best as reported to the Water Rocket Forum by the teams.

***World record status withdrawn when it was discovered that a non compliant parachute was used during record flights.
