Hughes H-4 Hercules

The biggest plane in the world ever to have flown is the Hughes H-4 Hercules (also know as the Spruce Goose). It was meant to be a heavy transport aircraft which could land on water. Only one has ever existed and it made its first flight on 2 November 1947. This first flight was also its last, as the project was cancelled. It really is HUGE, as you will see in the pictures below.

Here is a picture of a H-4 Hercules compared with a Douglas DC-3, from

This is some information on the H-4 from

Antonov An-225 Mriya

The biggest plane in the world flying today is the Antonov An-225 Mriya. This too is HUGE and it is actually longer than the H-4 Hercules. Its horizontal tail is wider than the wingspan of a Boeing 737. It is powered by six jet engines. It is Russian, built to carry the Russian version of the space shuttle, the Buran, on its back. In reality it is used more for other large transport jobs. It also sometimes flys at airshows. Only one has ever been completely built, another was half built but I think that the Russians gave up on that one. The half finished aircraft still exists… somewhere…
When the An-225 takes off, other aircraft at the airport waiting to depart have to wait 15 minutes afterwards before they can do so, as its huge jet engines create violent vortices in the air, making take off after it dangerous.

Bono, from the popular Irish rock band U2, once said after having seen an An-225 take off, “It’s bigger than a rock star’s ego”.

Both pictures below are of the An-225 with the Buran on its back, from



Picture below is not of the An-225, but of the Buran. As I have talked about it, I decided to include a picture of it. (In the background, you can see a MiG 25 Foxbat).

Below is a picture comparing the H-4, An-225, Airbus A380 and the Boeing 747. (I will definitely do a post soon about the Airbus A380 and the Boeing 747, two passenger jets which are extremely big, so keep checking for it).
